Hello, I'm trying to generate Apple mediastreamvalidator compliant HLS using ffmpeg and have very nearly achieved that.
The only remaining problem is that use of " -hls_flags iframes_only" correctly adds the #EXT-X-I-FRAMES-ONLY tag to my trickplay m3u8 but it doesn't increment the #EXT-X-VERSION value from 3 to 4. The validator then complains as follows: -------------------------------------------------------------------------------- MUST fix issues -------------------------------------------------------------------------------- Error: incorrect version number for feature --> Detail: Line: (null) --> Source: output_TrickPlay_Video_8bit.m3u8 If I manually edit the file and change the version value to 4, validation is successful. I have upgraded ffmpeg to the latest version but the problem remains. Is there a way for me to force #EXT-X-VERSION:4 ? Here is my command and the console output: ffmpeg \ -ss 00:00:00.000 -t 00:00:30.000 -i input_23.98fps.mxf \ -filter_complex \ "[0:v:0]format=pix_fmts=yuv420p[vconcat420p8bit]; \ [vconcat420p8bit]split=3[vconcat1][vconcat2][vconcat3]; \ [vconcat3]fps=1.001000[vconcat1fps]; \ [0:a:0][0:a:1]join=inputs=2:channel_layout=stereo[stereo]" \ -map "[vconcat1]" -f hls -hls_list_size 0 -hls_time 6.006 -hls_playlist_type vod -an -vcodec libx264 -flags +cgop -g 48 -b:v 2500k -maxrate 2500k -bufsize 2500k -x264opts nal-hrd=cbr:bframes=0:keyint=48:min-keyint=48:scenecut=-1 \ output_T0_Video_8bit.m3u8 \ -map "[vconcat2]" -f hls -hls_list_size 0 -hls_time 6.006 -hls_playlist_type vod -an -vcodec libx264 -flags +cgop -g 48 -b:v 250k -maxrate 250k -bufsize 250k -x264opts nal-hrd=cbr:bframes=0:keyint=48:min-keyint=48:scenecut=-1 \ output_T1_Video_8bit.m3u8 \ -map "[stereo]" -f hls -hls_list_size 0 -hls_time 6.006 -hls_playlist_type vod -vn -acodec libfdk_aac -b:a 120k -ar 48000 NEW_output_T1_Audio.m3u8 \ -map "[vconcat1fps]" -f hls -hls_list_size 0 -hls_time 6.006 -hls_playlist_type vod -hls_flags iframes_only -an -vcodec libx264 -intra -b:v 250k -maxrate 250k -bufsize 250k \ output_TrickPlay_Video_8bit.m3u8 \ ffmpeg version git-2021-01-13-f6477ac9 Copyright (c) 2000-2021 the FFmpeg developers built with Apple clang version 12.0.0 (clang-1200.0.32.28) configuration: --prefix=/usr/local/Cellar/ffmpeg/HEAD-f6477ac_6 --enable-shared --cc=clang --host-cflags= --host-ldflags= --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 --disable-libjack --disable-indev=jack --enable-opencl --enable-videotoolbox --disable-htmlpages --enable-libfdk-aac --enable-nonfree libavutil 56. 63.101 / 56. 63.101 libavcodec 58.117.100 / 58.117.100 libavformat 58. 65.101 / 58. 65.101 libavdevice 58. 11.103 / 58. 11.103 libavfilter 7. 95.100 / 7. 95.100 libswscale 5. 8.100 / 5. 8.100 libswresample 3. 8.100 / 3. 8.100 libpostproc 55. 8.100 / 55. 8.100 Guessed Channel Layout for Input Stream #0.2 : mono Guessed Channel Layout for Input Stream #0.3 : mono Input #0, mxf, from 'input_23.98fps.mxf': Metadata: operational_pattern_ul: 060e2b34.04010101.0d010201.01010900 uid : ec3f5416-a722-1dcc-8f60-d4f34e4a603d generation_uid : 296bd6eb-2ca9-1321-bbef-5f5f4cfc10ec company_name : Telestream Inc. product_name : Telestream Media Framework -
