ffmpeg does not support all file types

[elsabio]

Well the great news is that the statically linked ffmpeg (version N-51556-ge278500) included with UMS 2.6.1 will allow all my video media types (mkv, mpg, mv4 mostly) to be rendered correctly via a PS3.
The bad news is that it cannot render FLAC audio to my main music system (which is actually a Naim Uniti, but the HTTP headers are indistinguishable from the Phillips Streamium).
I have looked at the logs - even at Trace level, the output seems only to indicate a start and soon afterwards a stop event for each FLAC file.
I will gather the debug pack corresponding to this if anyone would like it attached to this thread.

However ... if I use the ffmpeg which is installed from the distro repositories on this Linux server (version 0.6.3-rpmfusion), I can play FLAC files just fine (and ogg, mp3, etc.) but cannot play m4v Video on a PS3.

So two questions ...

1. Can UMS be configured to use a different ffmpeg executable by file type? Or just by audio/video content perhaps?
2. If not - what needs to happen to get FLAC supported fully with the bundled ffmpeg binary?

I have tried building this from scratch, but this is such an old distro (based on Fedora 14), there are a lot of dependency hurdles to overcome - but if I can get the pieces to go with the ffmpeg build in 2.6.1, I'll try again. Otherwise, I might just write a trivial wrapper around my two ffmpegs, but that is really cheating!

Update:

Now I look at the trace while rendering video, it looks like ffmpeg is not being used for flac files at all. I thought this was being used to generate the stream data, but it appears not, so now I'm confused!

Update 2

So I'm probably wrong here. Looking at the HTTP headers sent, I see that a UPNP server that works in sending FLAC to the Uniti has headers like this:

Code: Select all

HTTP/1.1 206 Partial Content
Server: Logitech Media Server (7.7.2 - 33893)
Connection: close
Content-Length: 20214587
Content-Range: bytes 0-20214586/20214587
Content-Type: audio/x-flac
Content-Disposition: attachment; filename="03-Goehr-Suite_for_Violin_and_Piano_1_Prelude.flac"
TransferMode.Dlna.Org: Streaming

whereas UPNP (which does not) is sending this:

Code: Select all

HTTP/1.1 206 Partial Content
TransferMode.DLNA.ORG: Streaming
Content-Type: audio/mpeg
Content-Range: bytes 0-4360395/4360396
Accept-Ranges: bytes
Connection: keep-alive
Server: Linux-i386-2.6.35.14-106.fc14.i686, UPnP/1.0, UMS/2.6.1
Content-Length: 4360396

So does this Content-Type mean that some sort of transcoding has been done? If so, why is there nothing in the logs?


Mark.
