ffmpeg cmdline err: Could not find codec parameters (Video: [0][0][0][0] / 0x0000)

[spider-dan]

hello again,

i reconfigured a new VM with openmeetings 1.1 and now it seems that
the ffmpeg executable is visible in the PATH. unfortunately someting
else has gone wrong. the command to generate the flv for a recording
fails, and of course the recording can't be seen.

this is the command that openmeetings tries to execute:

ffmpeg
-i /usr/lib/red5/webapps/openmeetings/streams/6/
rec_2_stream_efa25a94ae383d8cafda46c046edcfc5_14_07_2010_17_56_44.flv
-i /usr/lib/red5/webapps/openmeetings/streams/6/
rec_2_stream_efa25a94ae383d8cafda46c046edcfc5_14_07_2010_17_56_44_FINAL_WAVE.wav
-ar 22050
-acodec libmp3lame
-ab 32k
-s 640x512
-vcodec flashsv
-map 0.0
-map 1.0
/usr/lib/red5/webapps/openmeetings/streams/hibernate/
flvRecording_2.flv

the output of the command:

could not find codec parameters

i configured ffmpeg with libmp3lame like this: ./configure --enable-
libmp3lame

has anybody a hint of any possible reason why these 2 errors occurr
( "Could not find codec parameters") ?


thank you very much,
dan

I have not seen this particular message before.
You should visit the FFMPEG list and post the Issue there.
They will be able to tell you right out of the box what this error message does exactly mean.

Works for me on Ubuntu 9.10. Just removed the ffmpeg I compiled from
source, installed it from the repository, added some additional
packages, and it works like a charm.
