Thread: cvlc cannot transcode to anything but h264

hi all,

i'm using cvlc transcode , stream (http) hvr-1250 capture card out other computers in house. streaming works if avoid transcoding , stream it's received. problem hd ~15mbit much. transcode down ~6-8mbit.

problem i'm having cvlc seems think don't have codecs available no matter try , transcode to. here's example commandline give cvlc:

code:

cvlc -vvv channels.conf -i http --http-host=xxx.xxx.xxx.xxx --http-src='/usr/share/vlc/lua/http/' --sout-keep --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=3000,ab=256,venc=ffmpeg{keyint=80,hurry-up,vt=800000},deinterlace}:std{access=http,mux=ts,dst=xxx.xxx.xxx.xxx:8181}'

when run receive following errors in output:

code:

[0x7f9280006fc8] stream_out_transcode stream out error: cannot find audio encoder (module:any fourcc:mpga). take few lines earlier see possible reason.  [0x7f9270001088] main generic debug: removing module "a52"  [0x7f9280006fc8] stream_out_transcode stream out error: cannot create audio chain  [0x7f9280560968] main decoder error: cannot create packetizer output (a52 )

i've installed libavcodec-extra-53 , restricted extras. i've enabled medibuntu repo , reinstalled ffmpeg there. right i've run out of ideas i'm crying out

if can assist i'd appreciate it.

thanks!

hi
try simplified commands eliminate things.

change this:-

code:

{vcodec=mp4v,acodec=mpga,vb=3000,ab=256,venc=ffmpeg{keyint=80,hurry-up,vt=800000},deinterlace}

to this:-

code:

{vcodec=mp4v,acodec=none}

then this:-

code:

{vcodec=mp4v,acodec=mpga}

if it's ok, add more options.
