#5487 closed patch (fixed)
LATM AAC audio stream support
| Reported by: | Owned by: | Janne Grunau | |
|---|---|---|---|
| Priority: | minor | Milestone: | 0.22 |
| Component: | mythtv | Version: | head |
| Severity: | medium | Keywords: | |
| Cc: | Ticket locked: | yes |
Description
The IsAudio? check in mpegtables.h is not returning true for stream id 0x11 (MPEG2AudioAmd1). This is the audio stream used for the New Zealand DVB-T freeview|HD platform. I believe Norway and other countries use this too.

Previsous patch along with LATM/AAC decoder
comment:3 Changed 16 years ago by
The patch above is a merge of the previous patch and the changes I have made to libavcodec to support LATM wrapped AAC for DVB-T channels.

Updated patches for 0.21-fixes.. Tested to compile properly
comment:5 follow-up: 7 Changed 16 years ago by
I didn't realise that the original patch depended on a newer version of ffmpeg and wouldn't compile with 0.21-fixes.
Updated the patch to compile with 0.21-fixes. I can not guarantee that it works unfortunately as I have no way of testing.

latm-aac.patch above is for trunk. This patch is vital for DVB-T in NZ, Norway and other now too. I, and others have been using the patch for many months without issue.

Patch for fixes has been successfully tested (also compatible with the 0.21 VDPAU patch)...

Have been struggling profusely to get working Freeview|HD here in NZ - LATM/HE-AAC, H.264. Certain channels crash the frontend on playback, and without P. Kendall's myth distro, there is no sound.
This patch does not work for me against the current revision of trunk.
What is keeping this issue from being resolved? Would be happy to help if I could.

I am currently getting my patches included in ffmpeg trunk.
Hopefully not too long till it's completed, then when Myth decides to move to trunk of ffmpeg this patch will note be needed.

Thanks for that Paul - can I please have your email address to discuss - I am currently attempting to build Myth trunk to use Freeview|HD for the main purpose of being able to use VDPAU.
I'm currently running your distro off your PPA, working perfectly apart from VDPAU - no idea how to get it going (or if it supports it?)
Can you please let me know what to do to get trunk working? I've got trunk from svn, got and built ffmpeg svn trunk, and applied the patch (including decoder) from this ticket. So far have got VDPAU working, and got great video from all channels but sound only from TV3.
Cheers!
P.S. Apologies for posting this in the ticket comments, pls feel free to delete after answering!

If this feature stands any chance of appearing in 0.22 we need a working patch against current trunk.
