I use vlc to transcoding a live stream. I use the follow command to start vlc: cvlc http://xxx.xxx.xxx.xxx/live --sout "#transcode{vcodec=h264,vb=2048,scale=0.5,acodec=mpga,ab=128,channels=2}:duplicate{dst=std{access=http,mux=ts,dst=:9000}}"
It works fine(VLC version: vlc-0.9.9a-5.el5.rf.i386), but when I upgrade VLC to the new one (Version:vlc-0.9.9a-7.el5.rf), I get errors: [00000510] avcodec encoder error: cannot open encoder [00000435] stream_out_transcode stream out error: cannot find video encoder (module:any fourcc:h264) [00000435] stream_out_transcode stream out error: cannot create video chain [00000508] main packetizer error: cannot create packetizer output (mpgv) So I use the follow command to start again: cvlc http://xxx.xxx.xxx.xxx/live -v 2 --sout "#transcode{vcodec=h264,vb=2048,scale=0.5,acodec=mpga,ab=128,channels=2}:duplicate{dst=std{access=http,mux=ts,dst=:9000}}" so I get more error infomation: [00000510] avcodec encoder warning: broken ffmpeg default settings detected (libx...@0x8374270) [00000510] avcodec encoder warning: use an encoding preset (e.g. -vpre medium) (libx...@0x8374270) [00000510] avcodec encoder warning: preset usage: -vpre <speed> -vpre <profile> (libx...@0x8374270) [00000510] avcodec encoder warning: speed presets are listed in x264 --help (libx...@0x8374270) [00000510] avcodec encoder warning: profile is optional; x264 defaults to high (libx...@0x8374270) [00000510] avcodec encoder error: cannot open encoder [00000435] stream_out_transcode stream out error: cannot find video encoder (module:any fourcc:h264) [00000435] stream_out_transcode stream out error: cannot create video chain [00000508] main packetizer error: cannot create packetizer output (mpgv) I use Google to find the solution, but i failed. Is there any bugs on VLC or ffmpeg or x264? -- Zhankao WEN (温占考) QQ: 616621 TEL: +86-13604079557 MSN: [email protected] Email: [email protected]
