MP4 streaming (H.264 + AAC / TS) issue 0.9.6/0.8.6i
Posted: 18 Nov 2008 18:34
vlc dshow:// :dshow-vdev="Osprey-210 Video Device 1" :dshow-adev="Osprey-210 Audio Device 1" :dshow-size="720x576" :sout=#transcode{vcodec=h264,venc=x264,vb=300,scale=0.5,acodec=mp4a,ab=128,channels=2} :duplicate{dst=std{access=udp,mux=ts,dst=224.255.1.1:1234}}
In the past this command was running well in 0.8.6i.
When I run version 0.9.6, I get the logging below:
main info: Start vlc met standaard interface. Gebruik 'cvlc' om vlc zonder interface te gebruiken.
main error: invalid chain
stream_out_transcode error: cannot create chain
main error: stream chain failed for `transcode{vcodec=h264,venc=x264,vb=300,scale=0.5,acodec=mp4a,ab=128,channels=2}'
main error: cannot start stream output instance, aborting
After further investigation, I have determined the following issues.
- some weeks ago, this command was running well. At that time I didn't have 0.9.6.
- At a certain moment, I got 0.9.4. I do not remember anymore how much I tested with this version.
- Last week I installed 0.9.6. At that time I couldn't stream anymore with the commandline.
- I several times uninstalled 0.9.6, installed 0.8.6i, 0.9.4 - sometimes Dutch, sometimes English version.
- Even with 0.8.6i I couldn't get the transcoding running again and got the same error message as with 0.9.6.
I got -- finally-- this problem solved in the following way:
- Install 0.9.6. with ALL options activated. So not only clearing preferences and cache, but install ALL the plugins.
- Uninstall 0.9.6.
- Install 0.8.6. with all options activated (but I am not sure whether this is necessary or not).
I strongly get the feeling this issue also is related to the fact that H.264 encoding doesn't work anymore in 0.9.6.
Fortunately 0.8.6i runs again, so this issue is solved yet.
