Hi.
I have problems with FFmpeg transcoding. It has similarities with the problem that "tubby" encounters but there are differences as well.
My setup:
Ubuntu 12.04
UMS 2.6.5
Channels 2.20
FFmpeg 0.10.7
My problem:
When playing SVTPlay on demand media FFmpeg stops with errors. Note that SVTPlay live media works fine - however PMSEncoder is invoked in that case. TV4Play works as well for some content - don't know which codec is chosen for that.
I started with the FFmpeg version that came bundled with UMS. However, that version obviously doesn't support the protocols used by SVT. So I created a symbolic link to the FFmpeg native version that I already had in my Ubunty environment and which has worked fine for playing SVT media with Serviio. However, the same version that works for Serviio doesn't work for UMS. By tracing both Serviio and UMS usage of FFmpeg, I found out the exact command used to invoke FFmpeg and the I run them directly from command in debug mode to get more information.
This is the result as called by UMS command string:

---- Note that despite these failures, the stream is correctly rendered by the TV!
The following is a highlight of the comparision:
- Serviio calls FFmpeg with the non transcoding option set for the video part whereas UMS calls FFmpeg with transcoding set to MPEG2 - this might be the major reason why Serviio succed whereas UMS fails.
- Given that trancoding is requested for UMS, a missing vbv buffer size can possibly be the reason why transcoding fails. However, this parameter is missing also in "tubbys" call to FFmpeg but it seems to be resolved somehow. I'd be glad to see an FFmeg debug from "tubby" to compare our versions of FFmpeg.
- The warnings in the beginning (which are also present in "tubbys" debug.log) are present both in the Serviio and FFmpeg invokations, so they are not of importance.
I'm basically stucked here and need some help to take it further. Please help!
Possible ways forward I have in mind are:
- Try to get UMS start FFmpeg without transcoding. I haven't found out a way to do this. Whereas it is possbible to exclude transcoding for file content in the config menu, the same possibility is not present for WEB content.
- Try to get (yet) another FFmpeg - possibly compiling one by myself. For this I would need to know the exact compiling directives used for a version that is known to work. To start with, maybee I could try "tubbys" version and see if I get the same problems. Or if there is anyone with a working FFmpeg in Linux - please send me your version and I will try it.
I also attach the debug.log, even if I think the command debugs contains much more information.
