your only real choices are aac and libfdk_aac and you can run multiple jobs in parallel this won't be any faster than reencoding if you're bottlenecked by the audio, but you won't lose any video quality if i ahve re-encode the audio anyway, wouldn't it be the same speed if I seperated them and muxed them back together after? also i meant pal to film, not pal to ntsc you do need to reencode the audio though yeah you can just remux the video stream with new timestamps if the source is h264 then you don't need to reencode you might be able to do that without reencoding there definitely isn't one in ffmpeg for aac any suggestions on a multithreaded audio codedc? my actual command line filtergraph uses lib-rubberband, so I can't actually use -c:a copy why would the default audio encoding be causing that then? your own to something sir, 2600 fps 75% usage now
ffmpeg -y -i input.mp4 -c:v libx264 -preset faster -crf 23 output.mp4 Either way it's still not loading the CPU But my custom build is x86, so that may be the difference. 1000 fps on the latest 圆4 static nightly build, cpu usage up to 40% now. i'll try something more official to rule that out i am using a year old or so custom build of ffmpeg. no no, i took the filters out to get that out of the equation you're probably being bottlenecked by the filters then my real command is much longer with a lot of filters, but even this simple one I get the same 30% or so CPU usage my command i'm using is ffmpeg -y -i input.mp4 -c:v libx264 -preset faster -crf 23 output.mp4 you can benchmark the decoder with ffmpeg -i foo.mp4 -f null. I checked my SSD and noticed nothing over 5% usage there But if that's the case, what is the bottleneck at the decoder level then? It can't be CPU. I'm wondering what the bottleneck is that I'm only getting this CPU usage? I've googled a bit and found out it could be because the decoder is not getting frames faster enough for the encoder? On a 4c/8t machine, I can only get ~30% CPU Usage. Hello, I'm trying to encode some low res content (between 320x240 and 640x480) using x264 and outputting at the same resolution. can i use ffmpeg to amplify an audio file? kerio: just fyi i am still laughing at the idea of an italian radiohead fan now it works, with `-c:a copy -c:v libx264` what type of person I must be to compile it myself, on windows. well, if you build it yourself, on windows. also idk how you even got a build of ffmpeg without libx264 but yeah that's still ffmpeg's default video codec in flv1 for some reason
isn't spark from the rang of animated gif? i assume every modern streaming site will laugh in your face if you try to send those codecs though
should I install/update anything or change parameters?

you might want to paste the full command there I'm getting error Bad audio codec 2 (Sorenson-H263). Next message (by thread): ffmpeg-devel.log.20170626.Previous message (by thread): ffmpeg-devel.log.20170625.
