Upgrade to > SVN 8696 breaks LiveTV [ DVB / XVMC (VLD/NVIDIA) ] — at Version 7

Description (last modified by danielk)

I've just upgraded both frontend (diskless EPIA M10k, Gentoo, 2.6.7) and backend from 8695 to SVN 8725.

Pre-recorded TV plays fine (recordings made before and after upgrade) but LiveTV fails. Here's the frontend log on entering LiveTV.

Cheers,

Jon

I have the same problem. I was using 8696, and XVMC broke after an upgrade. I am using the Nvidia 8178 driver. I fully purged my Myth build direcotires and re-built, but the problem persisted. I then reverted back to 8696 and it's back to working again without any problems. I've attached the relevant parts of the log and a backtrace.

Summary: Upgrade from SVN 8695 -> 8725 breaks LiveTV [DVB / XVMC-VLD]Upgrade to > SVN 8696 breaks LiveTV [ DVB / XVMC (VLD/NVIDIA) ]

I have exactly the same problem, except with the nVidia XvMC (driver version 7676). XvMC always worked until upgrading to 8725.

I deleted my source tree and checked out 8728 from scratch, which also exhibits the same problem. I have also re-installed my nVidia drivers to no effect.

I will look at attaching logs and a backtrace in about 12 hours when I get home from work (if it's not fixed by then :).

Obviously it's a commit that happened between 8696 and 8725, as the previous poster indicates.

Finding the exact checkin that broke things would be helpful.

Have perused the changesets, and decided that the most likely revisions at which this may have broken are....

8703
8704
8706
8717
8719
8722

Forgive my unfamiliarity with the codebase if this seems incorrect (this is a start, eh?).

I too am suffering from this problem. Most unpleasant visual glitch artefacts occur. The crash has a nasty habit of taking the whole box down. Yet recordings (from the same channel and the same programme that caused LiveTV to choke) work just fine.

I shall try 8706, then we will have halved the potential culprits.

I'm just building 8716 - it takes a while on my EPIA.

Please test with the latest SVN, in case [8737] fixed this.

I need a full "mythfrontend -v playback" log with the latest SVN anyway..
