troubles with stream transcoding
Posted: 17 Feb 2008 20:55
Hi all
I'm using Fedora 8 and vlc 0.8.6d to translate two DVB-channels into lan by http, and trying to use some codecs to compress the stream. Vlc start's by next line:
/usr/bin/vlc -vvv dvb:// --dvb-adapter=0 --dvb-frequency=11057000 --dvb-srate=26470000 --dvb-voltage=13 --ts-es-id-pid --ttl 12 --programs=1,800 --sout-transcode-vcodec=mp4v --sout-transcode-vb=512 --sout-transcode-acodec=mp3 --sout-transcode-ab=128 --sout='#transcode:duplicate{dst=std{access=http,mux=asf,dst=address1},select="program=1", dst=std{access=http,mux=asf,dst=address2},select="program=800"}'
I'm trying different combinations of container/codec, but video stream not compressing - users gets' 5-6 MBit stream on each satellite channel...
Audio stream on this channels comressing, all players show 128.0 kbit on requested stream, and client's player uses proper codec to play video - but....
I'm tried dump transcoded stream directly to local file - and getting the same result, 5-6 MBit per second of Video.
Then I'm installed vlc 0.8.6, 0.8.6b and 0.8.6d from sources - and had no effect...
Any advices or ideas..?
