#6471(avformat:new): RTMPS stream does not work

#6471: RTMPS stream does not work -------------------------------------+------------------------------------- Reporter: | Type: defect rubensanchez | Priority: important Status: new | Version: git- Component: avformat | master Keywords: rtmps, | Blocked By: facebook | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Using FFmpeg v3.3.1 and trying to open a stream to an RTMPS URL (Facebook with SSL actually) results in a few RTMP packets written to the output stream but then libavformat tries to read something in return. The thing is Facebook does not returns anything resulting in a connection hanged after 5-6 packets. I solved this issue with this: {{{ rtmpproto.c:3220 from: ret = ffurl_read(rt->stream, &c, 1); to: //ret = ffurl_read(rt->stream, &c, 1); ret = AVERROR(EAGAIN)); }}} This modification will force to not read anything from the server so the connection does not hang. With this fix I can see the RTMPS stream on Facebook Live preview and does not affect other RTMP streams. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6471> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10897: Assertion best_input >= 0 failed at fftools/ffmpeg_filter.c:1909 -------------------------------------+------------------------------------- Reporter: Andreas | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: I use a quite complicated filter expression to extract parts of a video and time-stretch these parts. It works fine with ffmpeg 4.0.2, but no longer in 6: 6.1 release loops forever and a recent build from master throws the above assertion error. How to reproduce: Run the commandline found in the log files - it is always the same command. I provide log files for 4.0.2 where it works, for 6.1 where I terminate the infinite loop via Ctrl+C after 10 minutes or so, and master with the assertion error. The problem is not related to the input video, I tried the same commandline with different videos, the result is always the same. For completeness you find one of the videos here: https://a-voss.de/ffmpeg/ It is also not platform dependent, I tried in Windows and Linux. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10897> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

I am not sure on the history of why the 5 byte skip is needed, but, if that skip is needed, might I at least recommend to change it to: if (pes->stream_type == 0x15 && pes->st->codecpar->codec_id == AV_CODEC_ID_SMPTE_KLV && buf_size >= 5) Thank you. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10883> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

The first five bytes of the first KLV stream key are being omitted from each packet. The same problem occurs when extracting the KLV data stream from the mpegts file: With ffmpeg 6.0: ./ffmpeg -i 'Day Flight.mpg' -c copy -map d -f data klv60.bin ./ls -la -rw-r--r-- 1 rmcnew rmcnew 977 Jan 27 11:39 klv60.bin With ffmpeg 6.1 development: ./ffmpeg -i 'Day Flight.mpg' -c copy -map d -f data klv61-dev.bin ./ls -la -rw-r--r-- 1 rmcnew rmcnew 947 Jan 27 11:40 klv61-dev.bin Again notice the size difference. This KLV data truncation corrupts the data stream since it leaves out the first five bytes of the KLV 'key' needed for KLV processing, decoding, etc. FFmpeg 6.0 details: ffmpeg version n6.0.1-1-g133069b434-20240127 Copyright (c) 2000-2023 the FFmpeg developers built with gcc 13.2.0 (crosstool-NG 1.25.0.232_c175b21) configuration: --prefix=/ffbuild/prefix --pkg-config-flags=--static --pkg-config=pkg-config --cross-prefix=x86_64-ffbuild-linux-gnu- --arch=x86_64 --target-os=linux --enable-nonfree --enable-gpl --enable- version3 --disable-debug --enable-iconv --enable-libxml2 --enable-zlib --enable-libfreetype --enable-libfribidi --enable-gmp --enable-openssl --enable-lzma --enable-fontconfig --enable-libvorbis --enable-opencl --enable-libpulse --enable-libvmaf --enable-libxcb --enable-xlib --enable- amf --enable-libaom --enable-libaribb24 --enable-avisynth --enable- chromaprint --enable-libdav1d --enable-libdavs2 --enable-libfdk-aac --enable-ffnvcodec --enable-cuda-llvm --enable-frei0r --enable-libgme --enable-libkvazaar --enable-libass --enable-libbluray --disable-libjxl --enable-libmp3lame --enable-libopus --enable-librist --enable-libssh --enable-libtheora --enable-libvpx --enable-libwebp --enable-lv2 --enable- libvpl --enable-openal --enable-libopencore-amrnb --enable-libopencore- amrwb --enable-libopenh264 --enable-libopenjpeg --enable-libopenmpt --enable-librav1e --enable-librubberband --disable-schannel --enable-sdl2 --enable-libsoxr --enable-libsrt --enable-libsvtav1 --enable-libtwolame --enable-libuavs3d --enable-libdrm --enable-vaapi --enable-libvidstab --enable-vulkan --enable-libshaderc --disable-libplacebo --enable-libx264 --enable-libx265 --enable-libxavs2 --enable-libxvid --enable-libzimg --enable-libzvbi --extra-cflags=-DLIBTWOLAME_STATIC --extra-cxxflags= --extra-ldflags=-pthread --extra-ldexeflags=-pie --extra-libs='-ldl -lgomp' --samples=fate-suite/ --extra-version=20240127 libavutil 58. 2.100 / 58. 2.100 libavcodec 60. 3.100 / 60. 3.100 libavformat 60. 3.100 / 60. 3.100 libavdevice 60. 1.100 / 60. 1.100 libavfilter 9. 3.100 / 9. 3.100 libswscale 7. 1.100 / 7. 1.100 libswresample 4. 10.100 / 4. 10.100 libpostproc 57. 1.100 / 57. 1.100 FFmpeg 6.1-development details: ffmpeg version N-113433-gbab7f91c36-20240127 Copyright (c) 2000-2024 the FFmpeg developers built with gcc 13.2.0 (crosstool-NG 1.25.0.232_c175b21) configuration: --prefix=/ffbuild/prefix --pkg-config-flags=--static --pkg-config=pkg-config --cross-prefix=x86_64-ffbuild-linux-gnu- --arch=x86_64 --target-os=linux --enable-nonfree --enable-gpl --enable- version3 --disable-debug --enable-iconv --enable-libxml2 --enable-zlib --enable-libfreetype --enable-libfribidi --enable-gmp --enable-openssl --enable-lzma --enable-fontconfig --enable-libharfbuzz --enable-libvorbis --enable-opencl --enable-libpulse --enable-libvmaf --enable-libxcb --enable-xlib --enable-amf --enable-libaom --enable-libaribb24 --enable- avisynth --enable-chromaprint --enable-libdav1d --enable-libdavs2 --enable-libfdk-aac --enable-ffnvcodec --enable-cuda-llvm --enable-frei0r --enable-libgme --enable-libkvazaar --enable-libass --enable-libbluray --enable-libjxl --enable-libmp3lame --enable-libopus --enable-librist --enable-libssh --enable-libtheora --enable-libvpx --enable-libwebp --enable-lv2 --enable-libvpl --enable-openal --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenh264 --enable-libopenjpeg --enable-libopenmpt --enable-librav1e --enable-librubberband --disable- schannel --enable-sdl2 --enable-libsoxr --enable-libsrt --enable-libsvtav1 --enable-libtwolame --enable-libuavs3d --enable-libdrm --enable-vaapi --enable-libvidstab --enable-vulkan --enable-libshaderc --enable- libplacebo --enable-libx264 --enable-libx265 --enable-libxavs2 --enable- libxvid --enable-libzimg --enable-libzvbi --samples=fate-suite/ --extra- cflags=-DLIBTWOLAME_STATIC --extra-cxxflags= --extra-ldflags=-pthread --extra-ldexeflags=-pie --extra-libs='-ldl -lgomp' --samples=fate-suite/ --extra-version=20240127 libavutil 58. 36.101 / 58. 36.101 libavcodec 60. 38.100 / 60. 38.100 libavformat 60. 20.100 / 60. 20.100 libavdevice 60. 4.100 / 60. 4.100 libavfilter 9. 17.100 / 9. 17.100 libswscale 7. 6.100 / 7. 6.100 libswresample 4. 13.100 / 4. 13.100 libpostproc 57. 4.100 / 57. 4.100 Build framework used: https://github.com/BtbN/FFmpeg-Builds Build options: ./makeimage.sh linux64 nonfree 6.0 ./build.sh linux64 nonfree 6.0 and ./makeimage.sh linux64 nonfree 6.1 ./build.sh linux64 nonfree 6.1 ***but adapted to point to cloned development branch Build operating system: Red Hat Enterprise Linux release 9.3 (Plow) running under WSL2 -- Ticket URL: <https://trac.ffmpeg.org/ticket/10828> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
