#MPEG4 NOT RECORDING AUDIO ICECREAM SCREEN RECORDER HOW TO#

The error message I'm getting is: Output #0, flv, to 'output.flv': I couldn't get it to work without -acodec aac -strict experimental, contrary to the HOWTO on ffmpeg wiki. This line works: FFmpeg/ffmpeg -video_size 1024x768 -framerate 25 -f x11grab -i :0.0+0,0 -f alsa -ac 2 -i pulse -acodec aac -strict experimental output.flv The solution seems to be to use both a different video and audio encoder. if it's a regression, which revision to build from.fixing my mistakes in the command line flags.

#MPEG4 NOT RECORDING AUDIO ICECREAM SCREEN RECORDER HOW TO#

If anybody can tell me how to get this to work by either: Stream #0:0 -> #0:0 (rawvideo (native) -> mpeg1video (native)) Like DVD, VCD or others, make sure you set the correct buffer size If you want the mpeg file to be compliant to some specification VBV buffer size not set, using default size of 130KB

Stream #1:0: Audio: pcm_s16le, 48000 Hz, 2 channels, s16, 1536 kb/sДЇile 'output.mpeg' already exists.
