Hi all,

with 2.0.4 version of VLC when i start a transcoding using MJPEG encoder and MPJPEG mux (vcodec=MJPG) i' ve following problem

avcodec error: cannot open encoder
stream_out_transcode error: cannot find video encoder (module:any fourcc:MJPG). Take a look few lines earlier to see possible reason.
stream_out_transcode error: cannot create video chain

Can you help me please?

Same problem here,
vlc 2.0.4 on windows 7 64 bit fails to transcode to MJPG using vcodec=MJPG and mux=MPJPEG . Output is the same as the previous post.

avcodec error: cannot open encoder
stream_out_transcode error: cannot find video encoder (module:any fourcc:MJPG). Take a look few lines earlier to see possible reason.
stream_out_transcode error: cannot create video chain

Pls note that this was working on 2.0.2 and 2.0.3 on the same machine.

as a note for followers, I get this message (with 2.0.5):

stream_out_transcode error: cannot find video encoder (module:any fourcc:MJPG)

when I set vb too high, like this:

vlc --no-audio dshow:// --dshow-vdev=screen-capture-recorder --dshow-adev=none --sout "#transcode{vcodec=MJPG,vb=5000,acodec=none}:standard{access=http,mux=mpjpeg,dst=localhost:8081/go.mjpeg}" :dshow-fps="1.000000"

but it works ok with vb=800

\vlc.exe" --no-audio dshow:// --dshow-vdev=screen-capture-recorder --dshow-adev=none --sout "#transcode{vcodec=MJPG,vb=800,acodec=none}:standard{access=http,mux=mpjpeg,dst=localhost:8081/go.mjpeg}" :dshow-fps="1.000000"

weird. I didn't seem to see anything in the logs to tell me "your vb is too high" either...feature request :)
