Pity that there still isn't any QuickSync encoding support (yes I know it is not as good as x264 but it has its uses for items like live transcoding for webstreaming).

Meanwhile libav guys didn't want to be behind their arch-enemy and released version 9 of the fork.

So will this allow the use of a capture card analog input that doesn't come with a hardware mpeg2 encoder? Cause I have a few of those lying around.

ffmpeg use x264 as an h264 encoder so i doubt that ffmpeg will ever support Quicksync or the encoding stuff from Amd or Nvidia

Does anybody know how to mux an ass subtitle with ffmpeg?
ffmpeg -i video.h264 -i audio.aac -i subtitle.ass -acodec copy -vcodec copy -scodec copy output.mkv didnt work :/ he say he cant do anything with the subtitle. and maybe if someone can tell me how to attach and file to the mkv would be awesome. currently i do this stuff with mkvtoolnix.

Sure why not? the question is only how to choose the channel

And that is a shame as for the purposes of streaming even a lowly i3 can easily encode multiple video streams realtime using quicksync and for purposes of wireless video mirroring it is pretty much a prerequisite without dropping your system to its knees.

You would still have to use the v4l interface to do that.

Not sure but check this:

That is to burn in the subtitle. i want only to insert it in the mkv container. so everyone one can choose to use the subtitle or not. if you burn in the sub he is encoded in the videostream and cant be disabled, removed or changed. BUt thanks that you looked for it.
