17 mai 2014, par batumanI am trying to stream video from my Raspberry PI using
ffserver, raspivid and ffmpeg
. My command is as followffserver -f /etc/ffserver.conf & raspivid -vf -t 0 -w 450 -h 200 -fps 25 -b 2000000 -o - | ffmpeg -f h264 -r 25 -c:v h264 -i - -c:v libx264 -c:a libmp3lame http://localhost:8090/feed1.ffm

As you can see the video is being saved with 200kbs no matter what option I set ; what am I doing wrong ?

[mxf @ 0x272de60] no essence
/tmp/TEST_4K.MXF: Invalid data found when processing inputThe file is quite large ( 30GB). Could this have something to do with this issue ? I googled for the no essence error but this doesn’t seem to provide any useful information. I checked the permissions on the file and those are not an issue. Also, I tried the same command for a smaller file (approx. 12 GB, which does work). Has anyone had any problems handling large files with FFMpeg ? Thanks !
