Differences 'sout' between vlc 0.8.1 and vlc 0.8.4 ??

[mordillo]

Hi,
first of all, I like to say sorry for my bad english.

I have a problem to receive a stream output from vlc to my settopbox.

With VLC Version 0.8.1, receiving is fine, and the movie is correctly playing.

With VLC Version 0.8.4 I have problems to receive some Xvid coded movies: Here is the log from vlc 0.8.4

Should I have to change the sout Options in another style since vlc 0.8.1 ?

The sout I send to vlc is:

#transcode{vcodec=mpgv,vb=2048,width=576,height=576,acodec=mpga,ab=192,channels=2}:duplicate{dst=std{access=http,mux=ts,url=:9090/dboxstream}}

If I understand the Messages right, then there where a problem with the mp4v encoder by using ffmpeg, but there are no Problems by opening the file pure with vlc ..

Have anyone heard about this Problem ?


Greetings

EDIT: I have read, that this is a known bug and should be solved in vlc 0.8.4, but it doesnt!!

Has no one an idea ?

23.9 fps aren't supported by MPEG1/2, so the encoder doesn't start. I've seen this already on the forum, but I don't know how to fix it actually.

[mordillo]

This was my first idea before I posted here, but that couldnt be the reason because, I´ve reencoded this file into 25fps with virtualdub, but it wont usually work.
Opening with 0.8.1 is fine ..

This *bug* (I dont know if it is?) is also in current Version 0.8.4.a

I had a similar problem but was able to fix it be changing to using div3 as the transcode video codec.

I fixed it by sending a sout paramter {fps=25} then streaming works proper
