  • Missing audio stream which is required by this ffm at Raspberry PI using ffmpeg

    17 mai 2014, par batuman

    I am trying to stream video from my Raspberry PI using ffserver, raspivid and ffmpeg. My command is as follow

    ffserver -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

    It looks working, I see the video displayed on the monitor and got the error as

    Missing audio stream which is required by this ffm

    The whole output at console is as follow.

  • FFMpeg : no essence (Invalid data found when processing input)

    8 mai 2014, par Flock Dawson

    I’m trying to convert a 4K MXF file to a low res WEBM file. I’ve upgraded FFMpeg and codecs to the latest versions. When I initiate the conversion, however, I get following error :

/tmp/TEST_4K.MXF: Invalid data found when processing input

    The 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 !
