I exported an empty CFLAGS variable, and configure succeeded. The same happened for x264. The compilation is not finished yet, but all looks fine to me. Could this behaviour be considered as a bug?

[FFmpeg-user] Compiling on an aarch64 machine
Hi,
I had already compiled ffmpeg on a 32bits OS for my aarch64 machine without
too much trouble, but now that I have a 64bits OS, I'd like to compile
ffmpeg too.
The issue I have is that gcc is started with bad options (I'm not sure of
that, that's what I think I understood):
mktemp -u XX
ZgAQ9I
test_ld cc
test_cc
BEGIN /tmp/ffconf.efsAigGe/test.c
1 int main(void){ return 0; }
END /tmp/ffconf.efsAigGe/test.c
gcc -mfpu=neon -c -o /tmp/ffconf.efsAigGe/test.o /tmp/ffconf.efsAigGe/test.c
gcc: error: unrecognized command line option '-mfpu=neon'
C compiler test failed.
poddingue@orangepi4-armbian:~/ffmpeg_sources/FFMpeg-orig$ ./configure
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this
will help
solve the problem.
gcc is unable to create an executable file.
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.
My gcc version is :
gcc -v
Using built-in specs.

Is there anything I could do with configure so that it uses the right
options?
Thanks.

Re: [FFmpeg-user] RTMP and proxy
Thanks a lot Moritz, I figured the option placement later on, I thought it applied to the whole command. And you're right, all is done so that I can't stream from inside the company to outside the company... except the company now wants to stream outside. I will try to get a SOCKS proxy installed... and will go on with my redsocks2 experiments (it worked on one machine) with the CONNECT proxy command.

Re: [FFmpeg-user] RTMP and proxy
Thanks. I have just recompiled ffmpeg with librtmp, and I now have access to the socks proxy option. Except my proxy is not a socks proxy. What about the -http_proxy option? Do I have to add a special option to configure to get ffmpeg to understand this option? Thanks.

Re: [FFmpeg-user] RTMP handshaking behind a proxy
I have given this command another try on another machine today, and read a
bit more about the handshaking process.
It does not seem to open any other port, just exchanging specific packets
on the 1935 port...
So something is fishy on my redsocks configuration I suppose...

[FFmpeg-user] How to terminate cleanly a recording on Windows
Hi there, I'm trying to record lots of small wav files to give to PocketSphinx for adaptation. My command looks like this: ffmpeg.exe -f dshow -i audio="Microphone sur casque (2- Plant" -acodec pcm_s16le -ac 1 -ar 16000 1.wav I haven't tried this particular command under Linux, but usually hitting "q" ends the recording properly. On Windows, "q" seems to do nothing, and CTRL+C ends the process, but not at the right time. Most of the time, I miss the end of the recording. My recordings are just a few seconds long. Would there be any clever way to end properly the recording on Windows? ffmpeg version git-2020-06-08-d29aaf1 Copyright (c) 2000-2020 the FFmpeg developers built with gcc 9.3.1 (GCC) 20200523 configuration: --enable-gpl --enable-version3 --enable-sdl2 --enable-fontconfig --enable-gnutls --enable-iconv --enable-libass --enable-libdav1d --enable-libbluray --enable-libfreetype --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libsrt --enable-libtheora --enable-libtwolame --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libzimg --enable-lzma --enable-zlib --enable-gmp --enable-libvidstab --enable-libvmaf --enable-libvorbis --enable-libvo-amrwbenc --enable-libmysofa --enable-libspeex --enable-libxvid --enable-libaom --disable-w32threads --enable-libmfx --enable-ffnvcodec --enable-cuda-llvm --enable-cuvid --enable-d3d11va --enable-nvenc --enable-nvdec --enable-dxva2 --enable-avisynth --enable-libopenmpt --enable-amf libavutil 56. 50.100 / 56. 50.100 libavcodec 58. 90.100 / 58. 90.100 libavformat58. 44.100 / 58. 44.100 libavdevice58. 9.103 / 58. 9.103 libavfilter 7. 84.100 / 7. 84.100 libswscale 5. 6.101 / 5. 6.101 libswresample 3. 6.100 / 3. 6.100 libpostproc55. 6.100 / 55. 6.100 Guessed Channel Layout for Input Stream #0.0 : stereo Input #0, dshow, from 'audio=Microphone sur casque (2- Plant': Duration: N/A, start: 99694.804000, bitrate: 1411 kb/s Stream #0:0: Audio: pcm_s16le, 44100 Hz, stereo, s16, 1411 kb/s File '1.wav' already exists.

Re: [FFmpeg-user] Extracting information from ffmpeg logs when streaming
Hi there,

[FFmpeg-user] RTMP handshaking behind a proxy
Hi there, I unfortunately have to stream from behind a proxy. It works on one of my machines thanks to redsocks. The RTMP handshake goes well, and I can stream to twitch or youtube. On another machine, with the same redsocks configuration, the handshake never finishes, be it with youtube or twitch. The ffmpeg command is just a copy of an already h.264 encoded stream from rtmp to rtmp. My question is: is there a random port opened for the negotiation? Where should I look for the blocking of the handshake? Here is the command I have and the output: ffmpeg -i "$SOURCE" -c:v copy -c:a copy -f flv "$YOUTUBE_URL/$KEY" -loglevel debug [...] Splitting the commandline. Reading option '-i' ... matched as input url with argument 'rtmp:// 192.168.1.217:1935/live/stream15'. Reading option '-c:v' ... matched as option 'c' (codec name) with argument 'copy'.

[FFmpeg-user] Extracting information from ffmpeg logs when streaming
Hi there, I'd like to extract the number of frames pushed when streaming with ffmpeg to a RTMP server. For the time being, I can see the number of frames in the console, and I read that the -report option could redirect that information to a file. I could then parse the file, and extract the frame numbers. Is there anything more straightforward?

Re: [FFmpeg-user] Add soft subtitles to YouTube Stream Now?
That's a very interesting subject (to me at least).

[FFmpeg-user] Producing several quality video streams from one 1080p stream.
Hi there, First of all, sorry for being vague, I don't have ffmpeg command line options yet, I'm just trying to know if I'm totally mistaken, or if my idea could be implemented quite safely/easily. I'm currently thinking of getting rid of YouTube for streaming within the company I work for (because YT consumes so much bandwidth, and you have not guarantee whatsoever about the quality, and even not talking about IP and so on). I could install big (but kind of old aka free) generic X86_64 servers in the server room, and using Kaltura on them, or even buy a fine piece of hardware that would do everything (it would take months to get the agreement), but I'd like to setup a POC first and foremost. I know ffserver has been abandoned, so it's out of the picture. I have lots of tiny and dirt cheap Linux ARM machines that can H.264 encode. I have machines producing content (which could be RAW, or H.264). So I thought of having the content producers multicast thanks to ffmpeg, and the small machines grabbing it, reducing the bitrate/quality, and then broadcasting to whatever machine could handle content delivery to the final user. I'm not so sure that's smart, as most of the video delivery software may want to do the downgrading by themselves. The goal of the POC would be to do most of the work on the edge of the network with ffmpeg (i.e. directly in the conference rooms) so that the server software could be hosted on the simplest, smallest and cheapest server with the simplest software possible to multicast. I suppose there are smarter ways with ffmpeg to get from a 1080p to lesser quality streams than just multicasting, encoding/downgrading, broadcasting to a server, and then multicasting. If you managed to read me until there, would you have any idea or recommandation?

[FFmpeg-user] Piping raw video from ffmpeg
Hi List, as stated in my previous message, the rkmpp h264 encoder has not yet been finalized, so I'm stuck for the moment. http://ffmpeg.org/pipermail/ffmpeg-user/2019-November/045991.html gstreamer has the hardware encoding part, so I thought of piping the output of ffmpeg (grabing an HDMI-IN pseudo-camera) to gstreamer for h.264 encoding, and then back to ffmpeg to stream to YouTube. Unfortunately, I have not been able to create the first part of the pipe. What I'd like to do is get the video in raw format, to avoid unnecessary CPU use and compression, and then give it to gstreamer to encode. So far, I have tried ffmpeg -f v4l2 -pix_fmt nv12 -s 1920x1080 -r 30 -i /dev/video0 -c:v rawvideo -f yuv - >/dev/null and got ffmpeg version N-95733-g73ee53f317 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 9 (Debian 9.2.1-19) configuration: --arch=arm --bindir=/home/linaro/bin --disable-stripping --enable-libaom --enable-avisynth --enable-avresample --enable-chromaprint --enable-frei0r --enable-gpl --enable-ladspa --enable-libass --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libdc1394 --enable-libfdk-aac --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libiec61883 --enable-libmp3lame --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-omx --enable-openal --enable-opengl --enable-sdl2 --enable-shared --incdir=/usr/include/arm-linux-gnueabihf --libdir=/usr/lib/arm-linux-gnueabihf --enable-nonfree --enable-rkmpp --enable-version3 --enable-libdrm --extra-cflags=-I/home/linaro/ffmpeg_build/include --extra-ldflags=-L/home/linaro/ffmpeg_build/lib --extra-libs='-lpthread -lm' --pkg-config-flags=--static --prefix=/home/linaro/ffmpeg_build libavutil 56. 35.101 / 56. 35.101 libavcodec 58. 62.100 / 58. 62.100 libavformat58. 35.100 / 58. 35.100 libavdevice58. 9.100 / 58. 9.100 libavfilter 7. 66.100 / 7. 66.100 libavresample 4. 0. 0 / 4. 0. 0 libswscale 5. 6.100 / 5. 6.100 libswresample 3. 6.100 / 3. 6.100 libpostproc55. 6.100 / 55. 6.100 [video4linux2,v4l2 @ 0xab664e80] The driver does not permit changing the time per frame [video4linux2,v4l2 @ 0xab664e80] Time per frame unknown [video4linux2,v4l2 @ 0xab664e80] Stream #0: not enough frames to estimate rate; consider increasing probesize Input #0, video4linux2,v4l2, from '/dev/video0': Duration: N/A, start: 0.00, bitrate: N/A Stream #0:0: Video: rawvideo (NV12 / 0x3231564E), nv12, 1920x1080, 1000k tbr, 1000k tbn, 1000k tbc [NULL @ 0xab6682b0] Requested output format 'yuv' is not a suitable output format pipe:: Invalid argument as a result.

Re: [FFmpeg-user] Using h264_mmal decoder on Raspberry Pi 4
Simon, there is a script there: https://www.raspberrypi.org/forums/viewtopic.php?t=199775 that could help you entering the right parameters to compile ffmpeg for the Raspberry Pi. Yes, it's a bit dated (ffmpeg 4.0.2 and Debian Stretch) but it worked for me. I did not say your parameters are not the right ones, I honestly have no idea, that's just in case... As for what ffmpeg says about hardware encoders/decoders, I think I understood that it will list what has been compiled, and not what is available on this particular machine.

Great. That was not crystal clear for me up to now. My first (reasonable) option would be to study the various systems I use, try to understand which hardware accelerators they have if any, and then choose the correct options in configure so that I will have a bespoke ffmpeg. I have already tried that path (more or less) with ARM SoCs, and my wounds have not healed yet. The second (harebrained) option would be to turn every hardware accelerator related option on with configure on every machine, so that I have a consistent ffmpeg build script, and then try to understand for each machine/build the hardware accelerators we have access to, if any (that would be once more a pain in the neck with ARM SoCs).

[FFmpeg-user] Listing the hardware accelerators
Hi List, I have different environments (X86, ARM, Jetson Nano) on which I'd like to use hardware encoders and decoders if available. I guess that I won't be able to use them if they have not been built in the ffmpeg dependencies if I install a "generic" version. Will the configure command autodetect what it should build, or do I have to know my hardware before launching configure with specific options? I have read https://trac.ffmpeg.org/wiki/HWAccelIntro but it's not clear to me yet. Is there any way to have ffmpeg list what it has "found" on my system? Do I have to launch a series of commands with the different accelerators that exist, and see the output? I suppose we have to specify on the command line the hardware acceleration chosen for the ffmpeg command, it won't autodetect and choose one that is available, am I right?

Re: [FFmpeg-user] ffmpeg to stream an already h.264 encoded stream
Thanks a lot Moritz, that did the trick.
So I now have:
ffmpeg -i "$SOURCE" -thread_queue_size 2048 -f pulse -i "$AUDIO_SOURCE"
-c:v copy -map 0:v:0 -map 1:a:0 -c:a libmp3lame -f tee
"[f=flv:onfail=ignore]$YOUTUBE_URL/$KEY|[f=flv:onfail=ignore]local_file.mkv"
which gives
Output #0, tee, to '[f=flv:onfail=ignore]rtmp://
a.rtmp.youtube.com/live2/my-key|[f=flv:onfail=ignore]local_file.mkv':
The output file is created, and the stream on YouTube is working too. I
don't know if MKV is the best format to use in this case.
I still have to figure out how to create a filename with a timestamp in it.
I had a look at the strftime option, but I don't know how to insert it into
the tee parameters.
I have another problem now, which is that the bitrate and the size have
disappeared:
frame= 4491 fps= 29 q=-1.0 size=N/A time=00:02:34.16 bitrate=N/A
speed=0.999x
I guess it's because of the tee. Is there any way to put them back on? It
was useful to check the streaming was going ok.

Re: [FFmpeg-user] ffmpeg to stream an already h.264 encoded stream
First of all, I don't know if I should continue within this thread or create a new one. It's all about the same subject, streaming and recording locally RTMP streams. Please let me know. So, for the time being, I am able to stream the h.264 encoded stream with the audio changed thanks to: ffmpeg -i "$SOURCE" -thread_queue_size 2048 -f pulse -i "alsa_input.usb-Focusrite_Scarlett_2i4_USB-00.analog-stereo" -c:v copy -map 0:v:0 -map 1:a:0 -f flv "$YOUTUBE_URL/$KEY" That's fine, I'm really happy with that. Now, I have to save the video on the disk too. So I had a look at the tee format, and issued that command: ffmpeg -i rtmp://192.168.1.212:1935/live/stream1 -thread_queue_size 2048 -f pulse -i alsa_input.usb-Focusrite_Scarlett_2i4_USB-00.analog-stereo -c:v copy -map 0:v:0 -map 1:a:0 -f tee "[f=flv:onfail=ignore]$YOUTUBE_URL/$KEY" ffmpeg version 4.2 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 7 (Ubuntu 7.4.0-1ubuntu1~18.04.1) configuration: --enable-gpl --enable-version3 --disable-static --enable-shared --enable-small --enable-avisynth --enable-chromaprint --enable-frei0r --enable-gmp --enable-gnutls --enable-ladspa --enable-libaom --enable-libass --enable-libcaca --enable-libcdio --enable-libcodec2 --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libjack --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librsvg --enable-librubberband --enable-librtmp --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtesseract --enable-libtheora --enable-libtwolame --enable-libv4l2 --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxvid --enable-libxml2 --enable-libzmq --enable-libzvbi --enable-lv2 --enable-libmysofa --enable-openal --enable-opencl --enable-opengl --enable-libdrm --enable-nonfree --enable-libfdk-aac --enable-libbluray --extra-libs='-lnettle -lhogweed -lgmp' libavutil 56. 31.100 / 56. 31.100 libavcodec 58. 54.100 / 58. 54.100 libavformat58. 29.100 / 58. 29.100 libavdevice58. 8.100 / 58. 8.100 libavfilter 7. 57.100 / 7. 57.100 libswscale 5. 5.100 / 5. 5.100 libswresample 3. 5.100 / 3. 5.100 libpostproc55. 5.100 / 55. 5.100 Input #0, flv, from 'rtmp://192.168.1.212:1935/live/stream1': Duration: N/A, start: 12094.717000, bitrate: N/A Stream #0:0: Video: h264, yuv420p(progressive), 1920x1080, 29.97 fps, 29.97 tbr, 1k tbn Stream #0:1: Audio: aac, 48000 Hz, stereo, fltp Guessed Channel Layout for Input Stream #1.0 : stereo Input #1, pulse, from 'alsa_input.usb-Focusrite_Scarlett_2i4_USB-00.analog-stereo': Duration: N/A, start: 1568128912.858773, bitrate: 1536 kb/s Stream #1:0: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s Automatic encoder selection failed for output stream #0:1.

Re: [FFmpeg-user] ffmpeg to stream an already h.264 encoded stream
Thanks a lot, I am now able to stream two videos at the same time with the computer doing almost nothing. Now, I have to replace the audio of the streams with what is coming from the FocusRite Scarlett 2i4 2nd generation, and lots of other things.

[FFmpeg-user] ffmpeg to stream an already h.264 encoded stream
Hi there, this is my first message on this list, so please bear with me. I have access to a h.264 encoder that will supply a few rtmp streams corresponding to the various HDMI inputs it has. It is supposed to use ffmpeg by the way (TBS2605). Anyway... I have a Linux machine, and my goal is to: - grab one of these streams, add audio coming from a USB sound card (FocusRite 2i4 2nd Gen), and stream that to YouTube while recording on the disk too. - grab two of these streams, compose them on top of a template, add audio (like in https://youtu.be/01nM2Shnyz0?t=1638), stream that to YouTube while recording on the disk too. For the time being, I have managed to stream to YouTube, but the YouTube platform is not happy with my stream quality, saying "The stream's current bitrate (1653.00 Kbps) is lower than the recommended bitrate. We recommend that you use a stream bitrate of 4500 Kbps.". The bitrate that is output by the encoder is supposed to be 4000Kbps. The ffmpeg command I have gives me around 2200/2400Kbps. So I guess I made a mess and decoded with my command the h.264 stream before encoding again... as the speed is around 0.962x, and the CPU is quite busy. I thought there was no need to decode/encode to add an audio stream (but I have no idea what I'm doing, as you had already guessed ;-) ). I recompiled the 4.2 ffmpeg release sources on this very machine. Here is the kind of output I get: ffmpeg version 4.2 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 7 (Ubuntu 7.4.0-1ubuntu1~18.04.1) configuration: --enable-gpl --enable-version3 --disable-static --enable-shared --enable-small --enable-avisynth --enable-chromaprint --enable-frei0r --enable-gmp --enable-gnutls --enable-ladspa --enable-libaom --enable-libass --enable-libcaca --enable-libcdio --enable-libcodec2 --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libjack --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librsvg --enable-librubberband --enable-librtmp --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtesseract --enable-libtheora --enable-libtwolame --enable-libv4l2 --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxvid --enable-libxml2 --enable-libzmq --enable-libzvbi --enable-lv2 --enable-libmysofa --enable-openal --enable-opencl --enable-opengl --enable-libdrm --enable-nonfree --enable-libfdk-aac --enable-libbluray --extra-libs='-lnettle -lhogweed -lgmp' libavutil 56. 31.100 / 56. 31.100 libavcodec 58. 54.100 / 58. 54.100 libavformat58. 29.100 / 58. 29.100 libavdevice58. 8.100 / 58. 8.100 libavfilter 7. 57.100 / 7. 57.100 libswscale 5. 5.100 / 5. 5.100 libswresample 3. 5.100 / 3. 5.100 libpostproc55. 5.100 / 55. 5.100 Input #0, flv, from 'rtmp://192.168.1.211:1935/live/stream0': Duration: N/A, start: 15024.271000, bitrate: N/A Stream #0:0: Video: h264, yuv420p(progressive), 1920x1080, 30 fps, 30 tbr, 1k tbn Stream #0:1: Audio: aac, 48000 Hz, stereo, fltp Guessed Channel Layout for Input Stream #1.0 : stereo Input #1, pulse, from 'default': Duration: N/A, start: 1568033472.683289, bitrate: 1536 kb/s Stream #1:0: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s Stream mapping: Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264)) Stream #0:1 -> #0:1 (aac (native) -> mp3 (libmp3lame)) Press [q] to stop, [?] for help [libx264 @ 0x559c4df3e780] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX FMA3 BMI2 AVX2 [libx264 @ 0x559c4df3e780] profile High, level 4.0 [libx264 @ 0x559c4df3e780] 264 - core 152 r2854 e9a5903 - H.264/MPEG-4 AVC codec - Copyleft 2003-2017 - http://www.videolan.org/x264.html - options: cabac=1 ref=3 deblock=1:0:0 analyse=0x3:0x113 me=hex subme=7 psy=1 psy_rd=1.00:0.00 mixed_ref=1 me_range=16 chroma_me=1 trellis=1 8x8dct=1 cqm=0 deadzone=21,11 fast_pskip=1 chroma_qp_offset=-2 threads=6 lookahead_threads=1 sliced_threads=0 nr=0 decimate=1 interlaced=0 bluray_compat=0 constrained_intra=0 bframes=3 b_pyramid=2 b_adapt=1 b_bias=0 direct=1 weightb=1 open_gop=0 weightp=2 keyint=60 keyint_min=6 scenecut=40 intra_refresh=0 rc_lookahead=40 rc=crf mbtree=1 crf=3.0 qcomp=0.60 qpmin=0 qpmax=69 qpstep=4 vbv_maxrate=7000 vbv_bufsize=512 crf_max=0.0 nal_hrd=none filler=0 ip_ratio=1.40 aq=1:1.00 Output #0, flv, to 'rtmp://a.rtmp.youtube.com/live2/dh5g-r8tf-x5qy-cse8': Metadata: encoder : Lavf58.29.100 Stream #0:0: Video: h264 (libx264) ([7][0][0][0] / 0x0007), yuv420p, 1920x1080, q=-1--1, 5000 kb/s, 30 fps, 1k tbn, 30 tbc Metadata: encoder : Lavc58.54.100 libx264 Side data: cpb: bitrate max/min/avg: 700/0/500 buffer size: 512000
