I am trying to use new CPU with VA-API enabled h264 encoder on FFmpeg (ffmpeg version n3.2.4-4-g36fff6c).
I have no issues encoding "offline" files with h264_vaapi encoder, but when I try to encode live streams and push output to SmoothStream server (using ISMV muxer) new streams do not work. Exactly same configuration works fine with libx264 encoder. So far I figured that after libx264 encoder ffmpeg correctly sets "CodecPrivateData" field data but h264_vaapi sends empty data field. Old command line (works fine): ffmpeg -y -i "udp://235.1.1.136:392" -g 30 -r ntsc -movflags isml+frag_keyframe -sc_threshold 0 -c:v libx264 -c:a aac -ac 2 -b:a 128k -b:v 3072k -f ismv "http://10.100.1.14/testenc1.isml/Streams(testenc1)" New command line (encoding works, but streams do not play): ffmpeg -y -vaapi_device /dev/dri/renderD128 -i "udp://235.1.1.136:392" -vf 'format=nv12,hwupload' -g 30 -r ntsc -movflags isml+frag_keyframe -sc_threshold 0 -c:v h264_vaapi -c:a aac -ac 2 -b:a 128k -b:v 3072k -f ismv "http://10.100.1.14/testenc1.isml/Streams(testenc1)" -- View this message in context: http://www.ffmpeg-archive.org/CodecPrivateData-is-empty-when-h264-vaapi-encoder-used-tp4679371.html Sent from the FFmpeg-users mailing list archive at Nabble.com. _______________________________________________ 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".
