ffmpeg fails in crontab running as root
21 décembre 2020, par Steve LloydI am trying to convert a video from mov to mp4 from a crontab.


/usr/bin/ffmpeg -y -nostdin -hide_banner -loglevel panic -i "/var/www/sample.mov" -vcodec h264 -acodec mp3 "/var/www/sample.mp4"



When I run it from a terminal it works fine. From a crontab I get the following errors. I have already tried adding "export LD_LIBRARY_PATH=/usr/lib/ && /usr/bin/ffmpeg" without success. Any help would be appreciated.


[h264_v4l2m2m @ 0x4e8290] Could not find a valid device
[h264_v4l2m2m @ 0x4e8290] can't configure decoder

Error while opening decoder for input stream #0:0 : Permission denied

ffmpeg says "No such file or directory" [closed]
10 octobre 2020, par srvnk

ffmpeg says no such file or directory but the file exists. I want to extract a frame/thumbnail from that video (pre1.mp4). I have installed ffmpeg by
sudo snap install ffmpeg
. My ubuntu version is 18.04.4 LTS. I also triedffmpeg -ss 00:00:01 -i pre1.mp4 -vframes 1 -q:v 2 output.jpg
but same error.

I am using php to generate the thumbnail. I tried functions -
exec
,shell_exec
andsystem
to run the command but same error. After getting error I tried to run the command in terminal but the error is same.
