[FFmpeg-devel] [PATCH] libavformat/dashenc.c:add support to change mpd update interval
Hello Mr.James For this , in dash if . there are tcs whose segment type is SegmentTemplate ,and minimumUpdatePeriod is not 50 . (eg: https://livesim.dashif.org/livesim/mup_30/testpic_2s/Manifest.mpd) Cause there is no rules in dash spec says , in template cases , the live miniupdateperiod should be 500s, So I modify my patch that , keep the 500 as the default minimumUpdatePeriod value , but add option to set this value for template cases B.R Huang Siyuan 0001-libavformat-dashenc.c-add-support-to-change-mpd-upda.patch Description: Binary data ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".

After that it can test whole system latency (from camera to client ) or said black box test . If there is other way which can burn ms level watermark , then maybe this patch no need . Here is my script to generate live stream with watermark : ffmpeg -i inputfile -an -vcodec libx264 \ -vf "drawtext=expansion=strftime:text='mspts':fontsize=50:fontcolor=yellow:box=1 :x=10:y=10:boxcolor=black@0.5:fontfile=./FreeSerif.ttf" ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
