There have been many bug fixes in that time. Please update it! Libaom version 3.2.0: https://johnvansickle.com/ffmpeg/release-readme.txt Libaom version 3.8.1: https://aomedia.googlesource.com/aom/+/refs/tags/v3.8.1 (The wiki at https://trac.ffmpeg.org/wiki/Encode/AV1 mentions alternative encoders but they seem to be experimental as they are not included in the published build.) -- Ticket URL: <https://trac.ffmpeg.org/ticket/10814> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10813: VP9 HLS encoding missing CODECS tag from playlist ---------------------------------+--------------------------------------- Reporter: alexpls | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------+--------------------------------------- When encoding a VP9 stream using the HLS segmenter, the CODECS tag does not appear within the HLS master playlist's #EXT-X-STREAM-INF. Here's an example command, and the playlist it produces: {{{ ffmpeg \ -i "Sintel_1080_10s_30MB.mp4" \ -c:v libvpx-vp9 -b:v 2000k \ -f hls \ -movflags frag_keyframe \ -hls_flags single_file \ -hls_segment_type mpegts \ -hls_list_size 0 \ -hls_time 6 \ -master_pl_name master.m3u8 \ -y \ encode/rendition_%v.m3u8 }}} {{{ #EXTM3U #EXT-X-VERSION:7 #EXT-X-STREAM-INF:BANDWIDTH=2200000,RESOLUTION=1920x818 rendition_0.m3u8 }}} Compare this to the behaviour for H.264 codec, where the CODECS tag is included: {{{ ffmpeg \ -i "Sintel_1080_10s_30MB.mp4" \ -c:v libx264 -b:v 2000k \ -f hls \ -movflags frag_keyframe \ -hls_flags single_file \ -hls_segment_type mpegts \ -hls_list_size 0 \ -hls_time 6 \ -master_pl_name master.m3u8 \ -y \ encode/rendition_%v.m3u8 }}} {{{ #EXTM3U #EXT-X-VERSION:4 #EXT-X-STREAM- INF:BANDWIDTH=2200000,RESOLUTION=1920x818,CODECS="avc1.640028" rendition_0.m3u8 }}} This seems similar to https://trac.ffmpeg.org/ticket/8904 I'm running ffmpeg version 6.1 on macOS Sonoma: {{{ ffmpeg version 6.1 Copyright (c) 2000-2023 the FFmpeg developers built with Apple clang version 15.0.0 (clang-1500.1.0.2.5) configuration: --prefix=/opt/homebrew/Cellar/ffmpeg/6.1-with-options_3 --enable-shared --cc=clang --host-cflags= --host-ldflags='-Wl,-ld_classic' --enable-gpl --enable-libaom --enable-libdav1d --enable-libmp3lame --enable-libopus --enable-libsnappy --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-libfontconfig --enable-libfreetype --enable-frei0r --enable-libass --enable-demuxer=dash --enable-opencl --enable-audiotoolbox --enable-videotoolbox --enable-neon --disable-htmlpages --enable-libfdk-aac --enable-nonfree }}} Thanks! -- Ticket URL: <https://trac.ffmpeg.org/ticket/10813> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10811: Typo in a deprecation warning from ffmpeg tool: says "enc_timebase" instead of "enc_time_base" -----------------------------------+---------------------------------- Reporter: Rinat | Type: defect Status: new | Priority: minor Component: ffmpeg | Version: 6.1 Keywords: docs typo | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+---------------------------------- Summary of the bug: Deprecation warning for `-enc_time_base -1` advises to use option `-enc_timebase` which does not exist.
