Hi!
Sorry for my English but i can't understand how slove this problem.

Computer P4 2.8 GHz
Memory 512 Mb
OS - Linux Debian 2.6.15.6
VLC 0.8.5
DVB-card SkyStar1-CI

I take the tv-channel from satellite and stream to my network.

Config file is:

Code: Select all

 param='dst=std{access=mmsh,mux=asfh,url=:3001},select="program=17"'

   /usr/local/vlc3/bin/vlc -vvv -I dummy --color --ttl 12  --ts-es-id-pid \
                --programs 17 dvb: --dvb-adapter=0 \
                --dvb-frequency=1293000 --dvb-srate=44948000 --dvb-voltage=13 --dvb-fec=7 --dvb-budget-mode \
                --sout "#transcode{vcodec=DIV3,vb=2000,width=640,height=480,croptop=8,cropright=6,cropleft=6,cropbottom=8,acodec=mp3,ab=128,channels=2,deinterlace}:duplicate{$param}"

All work great, but sometimes frames drop.

Code: Select all

000231] stream_out_transcode private debug: late picture skipped (1058)
[00000248] ts demuxer debug: pid[20] unknown
[00000231] stream_out_transcode private debug: late picture skipped (86717)
[00000231] stream_out_transcode private debug: late picture skipped (49478)
[00000231] stream_out_transcode private debug: late picture skipped (12859)
[00000231] stream_out_transcode private debug: late picture skipped (53059)
[00000231] stream_out_transcode private debug: late picture skipped (16080)
[00000231] stream_out_transcode private debug: late picture skipped (16085)
[00000231] stream_out_transcode private debug: late picture skipped (3407)

CPU used on 30%, memory used about 120 Mb (25%). I can't uderstand why picture skipped?

BUT!
If don't use DIV3 codec and stream the mpeg2 from satellite (without coding):

Code: Select all

param='dst=std{access=mmsh,mux=asfh,url=:3001},select="program=17"'

   /usr/local/vlc3/bin/vlc -vvv -I dummy --color --ttl 12  --ts-es-id-pid \
                --programs 17 dvb: --dvb-adapter=0 \
                --dvb-frequency=1293000 --dvb-srate=44948000 --dvb-voltage=13 --dvb-fec=7 --dvb-budget-mode \
                --sout "#transcode{acodec=mp3,ab=128,channels=2,deinterlace}:duplicate{$param}"

the frames is not drop!!

But this is not the end.
What is also strange!
If i take the other channel (for example 16 program instead of 17) from this satellite (and the same frequensy) and use the DIV3 codec - all work fine! Without drops!

Can anyone help me?

And second qwestion. Why crop is not work? If this not realise in current version VLC ( it seems to me i read it somewhere in this forum), when bug fixed and in which version?

I use

Code: Select all

#!/bin/sh
/bin/killall vlc
sleep 4
/usr/local/bin/vlc -I http --ttl 1 --ipv4 --vlm-conf /tmp/vlm3.conf --daemon -vvv --control logger --logfile /var/log/vlclog
cd /tmp/
sleep 4
/usr/bin/wget -q http://localhost:8080/vlm/
rm index.html

and

Code: Select all

new sat03 broadcast enabled
setup sat03 input "dvb:"
setup sat03 option dvb-frequency=3570000
setup sat03 option dvb-srate=3570000
setup sat03 option ts-es-id-pid
setup sat03 option sout-standard-mux=ts
setup sat03 option sout-standard-access=udp
setup sat03 option sout-standard-sap
setup sat03 option programs=1
setup sat03 output #duplicate{dst=std{url=239.90.3.1,name=SatTV-03-Kolyma-plus}, dst="transcode{vcodec=mp4v,scale=0.5,acodec=mpga,ab=64}:std{url=239.92.3.1,name=
SatTV-03L-Kolyma-plus}",select="program=1"}
control sat03 play
