The most difficult part, is to add float/half pixel format in ffmpeg, before adding an exr encoder. (for now ffmpeg exr decoder, decode data in 16bit (int) not in float) Martin ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
[FFmpeg-user] ffmpeg cross-compile
Hello, I try to cross-compile ffmpeg for my router using this toolchain https://github.com/Freetz/freetz. It is an alternative firmware for AVM routers (https://web.archive.org/web/20171105112501/http://freetz.org:80/wiki/help/howtos/common/newbie.en). I need support for 'https' and 'dash' (libxml2). I tested with ffmpeg-4.0.tar.bz2, libxml2-2.9.8.tar.gz and openssl-1.0.2o.tar.gz. openssl: ./configure --host=mips-linux-gnu --target=mips-linux CC=mips-linux-gcc AR=mips-linux-ar LD=mips-linux-ld RANLIB=mips-linux-ranlib --prefix=/home/user/ffmpeg-mips --without-zlib --without-python make make install libxml2: ./Configure linux-generic32 shared --cross-compile-prefix=mips-linux- --prefix=/home/user/ffmpeg-mips make make install ffmpeg: ./configure --prefix=/home/user/ffmpeg-mips --enable-cross-compile --cross-prefix=mips-linux- --arch=mips --target-os=linux --enable-openssl --enable-libxml2 --extra-cflags='-I/home/user/ffmpeg-mips/include -Wl,-rpath=/home/user/ffmpeg-mips/lib' --extra-ldflags='-L/home/user/ffmpeg-mips/lib -Wl,-rpath=/home/user/ffmpeg-mips/lib' --extra-cxxflags='-I/home/user/ffmpeg-mips/include -Wl,-rpath=/home/user/ffmpeg-mips/lib' --disable-mips32r2 --disable-mipsdsp --disable-mipsdspr2 --disable-mipsfpu I got this error: 'ERROR: libxml-2.0 not found using pkg-config'. But the freetz-toolchain does not contain pkg-config. Is it possible to use pkg-config from the Debian 9 host system? When calling ffmpeg's configure without '--enable-libxml2', there is no pkg-config error. But a warning: 'mips-linux-pkg-config not found, library detection may fail.'

May I interrupt this discussion and put forward the theory that the "listen" mode of ffmpeg's http protocol/muxer was not made for multiple connections? As far as I understand, it waits for one connection, and terminates once this connection is closed. The option "-multiple_requests" does persistant HTTP connections for other sub-protocols, and has nothing to do with some sort of "server" mode. What you are trying to achieve was once provided by ffserver (until it was recently discontinued). nginx might be one option, and I once heard of an ffmpeg based server similar to ffserver which serves only Matroska via HTTP, but I can't find the link.

The HTTP protocol can handle several connections, but it requires using a specific API. The ffmpeg command-line tool does not use that API, and therefore can only handle one connection.

Thank you very much. I noticed this error means vdsp functions themselves
can't call, but don't know how should I fix it.
By adding "-framework Accelerate" to Libs line in rubberband.pc, the error have
gone!!
(On macOS, vdsp functions are defined in Accelerate.framework)
- Libs: -L${libdir} -lrubberband
+ Libs: -L${libdir} -lrubberband -framework Accelerate
I'm so happy!!!
P.S.
I have tested rubberband function as follows:
./ffplay -i ~/Movies/test.mp4 -af rubberband=tempo=2
It's fun!!!

The reason is apparently that FFmpeg cannot know in advance where the necessary headers are installed. I will likely send a patch that would fix the issue for you (with --extra-cflags=/path/to/libxml) but there is a high chance that it will be rejected: Building for less common systems is unfortunately not welcome;-( My suggestion is you simply patch away the check from configure or edit config.h and config.mak after running configure to enable libxml2 and add the necessary path.

[FFmpeg-user] How to ffplay side-by-side 2 videos which are of different size?
Hello, If 2 videos do have the same width and height, one can view them side by side with ffplay -f lavfi "movie='LEFT.mp4',scale=iw/2:ih[v0];movie='RIGHT.mp4',scale=iw/2:ih[v1];[v0][v1]hstack" What now if the 2 videos are of different size??? I wish that my monitor is divided into 2 panes, left video being smaller that right one, if need be the smaller video will be black padded. Actually, I want to compare the output on the LEFT with a video with a low CRF and on the RIGHT with a video with a higher CRF but with upsaling. Videos to be compared ffmpeg -y -i "M4H03893.mp4" -vf "crop=in_w-36*20:in_h-10*20:18*20:3*20,hqdn3d" -c:a copy -c:v libx264 -crf 12 -preset:v slow -async 1 -t 153 "LEFT.mkv" ffmpeg -y -i "M4H03893.mp4" -vf "crop=in_w-36*20:in_h-10*20:18*20:3*20,hqdn3d,scale=-2:720" -c:a copy -c:v libx264 -crf 25 -preset:v slow -async 1 -t 153 "RIGHT.mkv" Thanks ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

The comments in the ticket are valid, and you should not be machine parsing the stderr output to get input information. The output is not guaranteed to be accurate (for example it shows a shorthand "29.97 fps" instead of 3/1001). Processing it requires additional tools or code, and the resulting processed output may be easily broken with a variety of assorted inputs. Use ffprobe instead: it is a proper tool for the job. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
Re: [FFmpeg-user] ffmpeg http protocol question
when add the output option ‘-write_xing 0’, the output file can play. But it cannot play when I use http protocol. My http server is simple, It can receive data and write data to file. Then I test it, it can not play. Only the mp3 file is bad, others mp3 file is ok when I transfer data with http protocol. And I check tcp transfer data with tcpdump, the transfer data size is the same as the file I receive data to save file. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
