Hi @georgius
i being test MP 1.4 with your files in 1st post.

Hello,

I had the same problem and try to parse freebox m3u file. I keep only url with "sd" at the end (because cannot get sound with "ld" url and "hd" does not work due to a too low ISP bitrate.

I join in attached file my freebox m3u file for TV that I am using, not all url are working but some are working good.

However, I cannot get radio streams from free correctly because free use mutiple tracks in a same rstp stream (1 url and several tracks, 1 tracks by radios).

How did you get MP 1.4 ? The official release is MP 1.3.0

I had the same problem and try to parse freebox m3u file. I keep only url with "sd" at the end (because cannot get sound with "ld" url and "hd" does not work due to a too low ISP bitrate.

i can look without problem HD channel (10 dB of attenuation)
For a same channel France 4 we have
- France 4 (bas débit) slow flow (Codec video : h264 / Audio : AAC ) = BUG
- France 4 (Codec video : H264 / Audio : MPEG2) = OK
- France 4 HD (Codec Video : H264 / Audio : AAC ) = BUG

Have you tried different AAC decoders and different audio renderer?
Just thinking this could be a codec compatibility issue, or an issue with the MP audio renderer.
georgius can confirm, but I suspect the DVB-IP filter would probably have no influence on whether the audio works or not.

At least you can see that the audio streams are present at TsWriter:

So again... I suggest to try different AAC decoders (Monogram, DivX, FFDShow) and different audio renderer (default DirectSound).

 

[azzuro]

Have you tried different AAC decoders and different audio renderer?

So is Codec issue
LAV audio : BUG
Monogram : BUG
FFDSHOW : not available for AAC
DIVX Codex : WORK

Use MPAR has not effect compared to default directshow.
missing to install Divx codec

Maybe worth to report to @nevcairiel and provide a sample recording.

 

[FreakyJ]

better tell @tourettes he has contact to nev as far as I know, nev was the last time active in 2011 here...

Hi

Sorry i had a MP crass and had to re install.
I had MDA** installed, but that tried to descramble the stream, so I reinstalled without, and the switchtime went down to about 3-4 sec.
this is the same as WMC
i don't much about streams, but would it be faster to use another type.
/BR shummi

From TV server log it seems that switching channel takes approx. 3 seconds, but one second is waiting for response of HTTP server.

Hello,
Is there a possible way to select audio track in a rtsp stream ?

No, it's not possible, IPTV source filter doesn't split source stream to separate tracks. For adding this feature I need some testing TS stream. I write you private message with necessary information.

 

[georgius]

I can confirm that IPTV filter doesn't have anything with sound issue. Everything that comes from stream is sent to other filters in graph. I also think that this is codec issue. IPTV filter has ability to dump raw TS file (in TV server log folder, file name will be mpiptv_output_dump_{GUID}.ts), just change in MPIPTVSource.ini option DumpRawTS to 1.
