FFMPEG Incredibly Slow On Windows Server 2016
1er août 2019, par Ben GardnerI have a t2.small (2GB RAM, 1 vCPU) Amazon EC2 instance running a process using FFMPEG. It runs just fine ( 30 fps) on my computer (i7, 12GB RAM), but at around 2 fps on the server. Here’s the command :
rescale_command = f'ffmpeg -i {srcVideo} -filter_complex \"scale={owidth}:{oheight}, setsar=1:1, pad={dim[0]}:{dim[1]}:{oofx}:{oofy}\" {destVideo}'
I’ve tried uninstalling and reinstalling ffmpeg/ffprobe
Edited per llogan’s request, I’ve also discovered that it’s relatively speedy towards the beginning (I’m rescaling 100 times over the course of the program) and slows down towards the end.
It utilizes 100% of the CPU even from the beginning, though.
Example command/output :
ffmpeg -i media/8-1-2019/hi/dl-107.mp4 -filter_complex "scale=607:1080, setsar=1:1, pad=1920:1080:656:0" media/8-1-2019/hi/sl-107.mp4

syncing a video file with audio using ffmpeg is returning a video without audio
31 juillet 2019, par abboodWhen I attempt to sync a .mov video with an .m4a audio file using ffmpeg like so
ffmpeg -ss 00:00:2 -i test.m4a -i test.mov -c:v copy -c:a aac -strict experimental output.mp4
it works like a charm. But right now I’ve recorded a usability test video using adobe XD, and it returned an .mp4 (MPEG-4) video and I manually recorded the audio using quicktimre returning a .m4a audio file.
Trying to merge them using ffmpeg is returning a video without any audio :
ffmpeg -i video.mp4 -i audio.m4a -c:v copy -c:a aac -strict experimental output.mp4
