Not transcoding into mp4v - missing a module on my pc?
Posted: 24 Nov 2006 22:24

Hi all
When I want to stream a device or file to QuickTime then only the audio works, no picture is showing up:
Code: Select all
:sout=#transcode{vcodec=mp4v,vb=256,scale=1,acodec=mp4a,ab=128,channels=1}:rtp{sdp=rtsp://127.0.0.1:9000/test.sdp}:
Why? Is it because I don't have the mp4v module on my winXP pc? (Using Vlc 0.9 nightly)
Getting this:
Code: Select all
[00000667] ffmpeg encoder error: cannot open encoder
[00000658] stream_out_transcode private error: cannot find encoder ((null))
[00000658] stream_out_transcode private error: cannot create video chain
[00000664] main packetizer error: cannot create packetizer output (I420)
Is there something about ffmpeg that I have not installed (yet)?

Have tried with different versions including the 0.9 SVN.
Getting the error in all versions and have deleted the whole directory before reinstall.
Can anyone help?

bitrate?

I had a very similar error. I spent an hour searching on the web before it crossed my mind to try changing the bitrate (duh!).
I changed it from 196 to 128 and the encoding worked like a charm. Have you tried that?
