Is there any way to speed up video transcoding using Nvidea GPU ?
20 avril 2016, par evilpandaI am looking to transcode about 500gb worth of .mp4 video files to .flv format. I was wondering if there is any way my to gtx 970’s could speed up this process. Otherwise i’m stuck with using a single i7 4790k.
Is there any type of NVIDEA gpu conversion program available ?
Any suggestions appreciated.

ffmpeg android : change the speed of video and audio
2 octobre 2015, par JohnI am working on Android platform with ffmpeg, I’ve built the ffmpeg and run as ’run-time’ command for my android app.
I’ve tested some function like video trim, it’s working :
ffmpeg -i /sdcard/vpai/in.mp4 -ss 5 -t 5 -c:v copy -c:a copy /sdcard/vpai/out.mp4
merge video and audio, also working :
ffmpeg -i /sdcard/vpai/in.mp4 -i /sdcard/vpai/in.mp3 -c:v copy -c:a copy /sdcard/vpai/out1.mp4
But when I try to speed up the video, it’s not working, the command is :
ffmpeg -i /sdcard/vpai/in.mp4 -filter_complex '[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]' -map '[v]' -map '[a]' /sdcard/vpai/output.mp4
I execute the exact same command on desktop, its working fine, but not working on the Android...
The error message :
Invalid stream specifier :"[v]".
Last message repeated 3 times
Stream map "[v]" matches no streams.Any one can help ?
