Hello

I have a problem with rendering a HD 1080i movie with latest version of kdenlive (I already manage to render films from my current camcorder).

error message is :
Using network protocols without global network initialization. Please use avformat_network_init(), this will become mandatory later.
[mpegts @ 0x1917260] parser not found for codec hdmv_pgs_subtitle, packets or times may be invalid.
Using network protocols without global network initialization. Please use avformat_network_init(), this will become mandatory later.
[mpegts @ 0x191e6c0] parser not found for codec hdmv_pgs_subtitle, packets or times may be invalid.

...



installation informations :
archlinux
kdenlive 0.8.2-2
mlt 0.7.6-1
mlt-python-bindings 0.7.6-1

anyclue ?

regards
Olivier

It seems to me like those lines are just warnings, should not prevent rendering. Can you render as a script (will save a file like $HOME/kdenlive/scripts/script00x.sh) and then from the terminal, do:

sh -x $HOME/kdenlive/scripts/script00x.sh

Thank you for you superfast answer.

rendering as a script would not crash but :
- video is 720*576 whereas my profile is hd1080...
- I still have no sound

here is log :

This parameter is not expected:

s=hd1080

Did you create the render profile yourself?

If you edited the profile manually, it should give the size in pixels, for example: s=1920x1440

Also, the video bitrate parameter should read "vb=25000k" instead of "b=25000k"

Thanks a lot for your help.
I changed "b=25000k" in "vb=25000k" and now my render is fine.

but for my curiosity : I kept s=hd1080 and it works fine when I render to file but not when I render as a script and execute the script (rendered as 720*576)....

what is the difference between rendering to a file and as a script ? I thought both would use MELT in the same way...

Hmm, I don't know why it behaves differently between file and script. Both are supposed to call melt with the same parameters, but there might be some parameter parsing that is slightly different before calling melt...
