optimization of theora contract job
...ding with the existing theora/ffmpeg.
Right now we have to downsample 1080 to 480 before we can transcode, so it becomes a two-step ffmpeg process to get a 480 ogg/theora/vorbis done in realtime:
One proc:
ffmpeg -deinterlace -sws_flags bilinear -i - -vcodec mpeg2video -f mpegts -vb 3000000 -s 852x480 -acodec copy -v 0 -async 2 -croptop 5 -padtop 5 -padcolor 000000 -
Another proc:
ffmpeg -sws_flags bilinear -i - -vcodec libtheora -f ogg -vb 704000 -r 14.00 -s 852x480 -aspect 16:9 -acodec libvorbis -ar 44100 -ac 2 -ab 64000 -v 0 -async 2 -
This would be a contract job hourly starting within...
