No sound in internal DVD player when playing DVD with mp2 audio

Reported by: henrik-mythtv@… Owned by: markk
Priority: minor Milestone: unknown
Component: MythTV - DVD Playback Version: 0.23rc1
Severity: medium Keywords:
Cc: Ticket locked: no

Description

A DVD with multiple titles - e.g. one created with MythArchive? to backup multiple episodes of a series - does not have any sound when played with the internal DVD player. Sound is present on the title page, but when a title is selected only the image plays, there is no sound.

This happens when playing ISO-images of DVD's. Haven't tested with physical media.

This happens with DVD's created both with MythTV 0.21 and 0.22, when played with the 0.22+fixes internal DVD player.

The attached ISO file illustrates the problem - it has two titles. Just drop it into your "videos" directory and play it with the internal player.

set sample_rate if sample_rate is zero. not sure this is a good solution because the channels are set somewhere else. Need to locate where the channels are set and set the sample rate there too.

I've just managed to get .iso playback working in 0.22-fixes after a StorageGroup?/obsolete-username problem.

This example behaves just as mine do - sound in the recordings works if the menu is displayed for a few tens of seconds, until after a selection box repaint. I had thought it might be because I use mp2 sound throughout. Looking forward to seeing the fix!

(In [24018]) internal dvd player. Refs #8260 incorrect audio track id returned if audio stream is mp2. this was missed when [23079] was commited.

Running 0.23-230_rc2_r24029.fc12@x86_64 from ATrpms, the recordings in the sample .iso file do not play at all. Mine behave similarly. Perhaps this is what you saw in comment 5? Brief sample of log:

Looks like it might have been fixed.

This may be fixed in master but I've never been able to reproduce the issue and the code has changed a lot since 0.21/22.

If this still an issue, please open a new ticket with new logs.
