FFMpeg produces low quality target file with just 1 second length on Ubuntu 20.04
16 juillet 2021, par MattI'm using FFMpeg locally on a Mac (actually using PHP-FFMpeg) and it's working perfectly. I'm running the same code on an Ubuntu server and whatever I try the output file is a tiny, low quality video with just 1 second length (the original is about 15 seconds).


I installed it on the server with


sudo apt update
sudo apt install ffmpeg



and then restarted the server. To test now I'm running


ffmpeg -i source.mp4 target.mp4



from the terminal and getting this output

Using FFMPEG with PHP via shell_exec
23 février 2018, par Peter FriedlanderTrying to scan a directory fill of MPEG files and make framegrabs out of them using PHP.
$e= shell_exec('find . -regex ".*\.\(mp4\)" -exec bash -c \'/home3/tcokchal/public_html/ffmpeg3/ffmpeg-git-20180222-64bit-static/ffmpeg -i {} -vf fps=1/8 \{}Frame55Grab%d.png\' - {} \; 2>&1 ' );
This only returns
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Im trying to automate the process of a local shell script
find . -regex ".*\.\(mp4\)" -exec ffmpeg -i {} -vf fps=1/8 {}Frame55Grab%d.png \;
Which works

I tried :



ffmpeg -i test.m4v -acodec copy -vcodec copy -sn nodata.mp4




Data track still there, just moved from stream 0 to stream 2



I tried also :



ffmpeg -i test.m4v -acodec copy -vcodec copy -map 0:1 -map 0:2 no2.mp4




Same result, track still there, just jumped to stream 0:2 no luck.



Any hint ?
Thanks in advance
