[FFmpeg-user] Receive network stream and drop without decoding
Hello, trying to do something like "DASH load generator" for testing. Trying to simulate DASH client on unencrypted stream (using public stream in examples, should be accessible from anywhere): ffplay -nodisp -vst 3 -an -i 'http://download.tsi.telecom-paristech.fr/gpac/dataset/dash/uhd/dashevc-ondemand-4s/dashevc-ondemand-4s-p60.mpd' - this works and displays no video, but eats 40-50% of CPU core. Recompiled latest git pull with debug symbols, ran perf, top 4 CPU users: 9.01% ff_h264_decode_mb_cabac 6.66% decode_cabac_residual_nondc_internal.isra.4 6.16% loop_filter 5.19% get_cabac So, it is clearly doing decoding even with -nodisp and -vn options (-vn makes no difference). On IRC i got suggestion to use ffmpeg instead of ffplay: ffmpeg/bin/ffmpeg -hide_banner -vn -an -i http://download.tsi.telecom-paristech.fr/gpac/dataset/dash/uhd/dashevc-ondemand-4s/dashevc-ondemand-4s-p60.mpd -f null - ..then it fails with: Output #0, null, to 'pipe:': Output file #0 does not contain any stream If i skip -vn and -an - it works without problems (i see traffic flowing) but eats even more CPU (~70%) So far this is not suitable as "fake client" as server can handle thousands clients, but "client server" can barely handle 100 connections. Is there any way to tell ffmpeg to receive stream (network traffic) and discard it immediately, without decoding? ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

That means apt would have both after your install command, and cannot do that. You may need to de-install libavcodec57 and install libavcodec-extra57 in one step, or de-install the former first (also breaking packages which depend on it), then install the latter.

Re: [FFmpeg-user] ffmpeg drops 360 video metadata
Thank you for your quick response. Let me clarify what I am looking for. I want to stream 360 degree video over rtmp port and nginx server is in the backend. I want to demonstrate dynamic bitrate adaptation(such as HLS/DASH) . non-360 degree video streaming is working as expected, However I have difficulty with 360 video. I tried following ways 1. ffmpeg -loglevel verbose -i R0010309_er.MP4 -vcodec libx264 -strict unofficial -vprofile high -acodec aac -f flv rtmp://localhost/live/360streamR able to play stream at the sink but not playing in 360 degree mode because 360 degree video metadata is lost while format conversion (attached log 1) 2. ffmpeg -loglevel verbose -i R0010309_er.MP4 -preset veryfast -g 25 -sc_threshold 0 -map v:0 -c:v:0 libx264 -strict unofficial -b:v:0 2000k -map v:0 -c:v:1 libx264 -strict unofficial -b:v:1 6000k -map a:0 -map a:0 -c:a aac -b:a 128k -ac 2 -f hls -hls_time 4 -hls_playlist_type event -master_pl_name R3601.m3u8 -var_stream_map "v:0,a:0 v:1,a:1" /mnt/hls/R360Stream1_%v.m3u8 still same behaviour (log attached 2) Could you suggest a way where I can stream 360 degree video without losing spatial metadata and able to demonstrate bit rate adaption.

What is the recommended solution? ffmpeg doesn't have the concept of plugins, so there's only a defined set of codecs/filters/formats a compiled library can support. If this packaging is anything like in Debian/Ubuntu, those packages are either/or. Either you install the one with e.g. "fewer" codecs, or the one with "more".

[FFmpeg-user] timeout error when reading RTSP/RTP incoming audio stream
Hello I am struggling to read a multicast audio RTP stream controlled by RTSP. As soon as I launch the ffplay or ffmpeg command, the RTP traffic starts (tcpdump) on port 5004/UDP (as advertised in the SDP file), so it should read the stream correctly but I finally get a time-out instead (and empty out file). The very same RTSP URL can be read without any issue with VLC or with rtpdump+sox. $ ffmpeg -y -rtsp_transport udp_multicast -i "rtsp:// 192.168.2.148:554/by-name/AES67-stream (on hasseb-AoE-F8-82)" -vn -f s24le -ar 48000 -c:a pcm_s24be out.raw ffmpeg version 4.2.2 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 7 (Ubuntu 7.4.0-1ubuntu1~18.04.1) configuration: --extra-libs=-ldl --prefix=/opt/ffmpeg --disable-debug --enable-nonfree --enable-gpl --enable-version3 --enable-libopencore-amrnb --enable-libopencore-amrwb --disable-decoder=amrnb --disable-decoder=amrwb --enable-libpulse --enable-libfreetype --enable-gnutl s --enable-libdav1d --enable-libx264 --enable-libx265 --enable-libfdk-aac --enable-libvorbis --enable-libmp3lame --enable-libopus --enable-libvpx --enable-libspeex --enable-libass --enable-avisynth --enable-libsoxr --enable-libxvid --enable-libvidstab --enable-libtheora --en able-libwavpack --enable-libopenjpeg --enable-libgsm --enable-nvenc --enable-libzimg --enable-libaom 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 Guessed Channel Layout for Input Stream #0.0 : stereo Input #0, rtsp, from 'rtsp://192.168.2.148:554/by-name/AES67-stream (on hasseb-AoE-F8-82)': Metadata: title : AES67-stream (on hasseb-AoE-F8-82) streamed by "hasseb" Duration: N/A, bitrate: 2304 kb/s Stream #0:0: Audio: pcm_s24be, 48000 Hz, stereo, s32 (24 bit), 2304 kb/s Stream mapping: Stream #0:0 -> #0:0 (pcm_s24be (native) -> pcm_s24be (native)) Press [q] to stop, [?] for help rtsp://192.168.2.148:554/by-name/AES67-stream (on hasseb-AoE-F8-82): Connection timed out Output #0, s24le, to 'out.raw': Metadata: title : AES67-stream (on hasseb-AoE-F8-82) streamed by "hasseb" encoder : Lavf58.29.100 Stream #0:0: Audio: pcm_s24be, 48000 Hz, stereo, s32 (24 bit), 2304 kb/s Metadata: encoder : Lavc58.54.100 pcm_s24be size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x video:0kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used) The SDP file is : v=0 o=- 254522267104 0 IN IP4 192.168.2.148 s=AES67-stream (on hasseb-AoE-F8-82) streamed by "hasseb" t=0 0 a=clock-domain:PTPv2 0 a=recvonly m=audio 5004 RTP/AVP 98 c=IN IP4 239.123.123.123/255 a=rtpmap:98 L24/48000/2 a=sync-time:0 a=framecount:48 a=source-filter: incl IN IP4 239.123.123.123 192.168.2.148 a=ts-refclk:ptp=IEEE1588-2008:00-10-4b-ff-fe-2e-f8-82:domain-nmbr=0 a=mediaclk:direct=0 a=ptime:1 Comparing those files, we see that ffmpeg detects the correct audio settings (pcm_s24be, 48000 Hz, stereo, s32 (24 bit)) so I cannot figure out why it can't read the data stream? I have tried to increase the timeout but that did not help. Any help would be appreciated. Thank you.

I tried it another way, using split with trim filter to extract specific frames, then looping them individually, then concat filter to merge the video streams. This alternative approach still produces a 149 frame file. The exact same binary file as the above (according to "diff -b"). [0]null[layer_0]; [1]null[layer_1]; [layer_1]split=4[s1][s2][s3][s4]; [s1]trim=start_frame=0:end_frame=15,setpts=expr=PTS-STARTPTS[l1]; [s2]trim=start_frame=15:end_frame=16,setpts=expr=PTS-STARTPTS,loop=loop=104:start=0:size=1[l2]; [s3]trim=start_frame=16:end_frame=31,setpts=expr=PTS-STARTPTS[l3]; [s4]trim=start_frame=31:end_frame=32,setpts=expr=PTS-STARTPTS,loop=loop=14:start=0:size=1[l4]; [l1][l2][l3][l4]concat=n=4,setpts=expr='N/(30*TB)'[layer_1_loopedFrames]; [layer_0]fps=fps=30.00[layer_0_fps]; [layer_1_loopedFrames]fps=fps=30.00[layer_1_loopedFrames_fps]; [layer_0_fps][layer_1_loopedFrames_fps]overlay=x=0.0:y=0.0:format=auto[overlay_all] And, as previously mentioned, if I repeat the last frame one more time than necessary, it produces a correct 150 frame output. [0]null[layer_0]; [1]null[layer_1]; [layer_1]split=4[s1][s2][s3][s4]; [s1]trim=start_frame=0:end_frame=15,setpts=expr=PTS-STARTPTS[l1]; [s2]trim=start_frame=15:end_frame=16,setpts=expr=PTS-STARTPTS,loop=loop=104:start=0:size=1[l2]; [s3]trim=start_frame=16:end_frame=31,setpts=expr=PTS-STARTPTS[l3]; [s4]trim=start_frame=31:end_frame=32,setpts=expr=PTS-STARTPTS,loop=loop=15:start=0:size=1[l4]; [l1][l2][l3][l4]concat=n=4,setpts=expr='N/(30*TB)'[layer_1_loopedFrames]; [layer_0]fps=fps=30.00[layer_0_fps]; [layer_1_loopedFrames]fps=fps=30.00[layer_1_loopedFrames_fps]; [layer_0_fps][layer_1_loopedFrames_fps]overlay=x=0.0:y=0.0:format=auto[overlay_all] Notice, the loop of 15 (should be 14) in the [s4]...[l4] filterchain Different approach, same unexpected/wrong output.
