Description (last modified by )
I updated all three frontends. The main frontend (opensuse 11.2, digital audio) which is also the MB crashes upon starting certain video files. The other two frontends (opensuse 11.3, analog audio) don't have this problem. AVIs with xvid video and mp3 audio play fine. Most mkvs with avc video and AC3 audio crash. mkvs with avc video and AAC audio play fine.
A film that crashes has:

You can follow the instructions here:

or per section 22.2 of our manual.

The commit that breaks my system is d019ea. It works fine up and including d392ee.

SHA: d019ea is a merge from master to another branch. How could it work in SHA: d392ee but not SHA: d019ea if using master makes no sense whatsoever. You must have made a mistake somewhere when tracking the *"bug" as no code in master is modified between those two commits unless you do not use master.
Looking at the backtrace, you have an non-updated/recompiled libmyth (the number of arguments provided to AddData doesn't match the current code).
Make sure you run make distclean ; then re-do a configure.
This sounds more like a compilation issue than anything else.
Typically what would happen if you ran different version of libmythtv and libmyth
comment:8 by , 15 years ago
Further to jy's remarks, I removed /usr/share/mythtv, /usr/include/mythtv, /usr/lib/mythtv.
I searched for any *myth* reference and deleted it, too.
I cloned the master git repo again, compiled a debug version and installed again. The problem remains.
If I run git checkout d392ee, the resulting installation plays videos normally.
Anything above that checkpoint and the specific videos don't start. I am including a newer gdb.txt just in case anything is different. I don't think there is any more garbage left (although before this cleanup I found /usr/lib/libmythtv-0.23.so and libmythpostproc-0.23.so )
I would appreciate any input you may have. If you still think this is *my* problem and not a bug, let me know and I will write to the users' list. I know this is not a support forum.
Thanks again,
Yianni

There is still the same issue, that two function calls do not get the same argument between the caller and the callee. This will happen as the API changed recently (AddData takes a fourth argument). libmythtv calls add data with 4 arguments, yet adddata expects 3.
I would check again that you have run make distclean followed by configure again and that there aren't old libmyth*.so hanging in the ldconfig path.
The crash occur is due to the buffer provided to toFloat16 not being 16 bytes aligned, which isn't possible as that buffer is allocated to be 16 bytes aligned (allocated using av_malloc)
comment:10 by , 15 years ago
Just had a thought: can you provide the log generated by mythfrontend with -v audio,playback and play a file that crash. And post the entire output
comment:11 by , 15 years ago
What are your audio settings? (all of them) Did you enable software volume control ?

Disable passthrough only if using the software volume controller.
If using another type of mixer; as it will be ignored we can passthrough. Alternatively, if Myth Volume control was checked, but nothing else was configured; it could have resulted in a bug (try to passthrough, but would enable audio processing).
Fixes #9688

Sorry for the delayed response: My sound settings are: Device: Alsa:iec958:CARD:NVidia,DEV=0
DD=Yes, DTS=Yes, E-AC3=No, TRUE HD=No, DTS-HD=No
Speaker configuration: 5.1
Upconvert Stereo to 5.1 Surround: Yes
Upmix Quality: Best
Advanced Audio Settings
Override SRC Quality=No Force 48kHz=Yes, SPDIF 48k rate override=No
Separate Digital Audio Device=No
HBR Passthrough Support=Yes
Mixer: Use Internal Volume Controls=Yes
Mixer Device=software Mixer Controls=Master
I have been using these settings for quite a while now without a problem.
I am now at the 52ac546 commit and the problem goes away only if I change the mixer device to anything but software. With software it crashes still.
So, for my specific configuration it hasn't been fixed.
Has the audio configuration changed in such a way that I can no longer use the software mixer? It's not that big a deal but it's some loss of functionality (another remote instead of just the rf keyboard).
Thanks for all your efforts, again.

Can you provide the following info: *mythfrontend --version *Another backtrace *try playing the same file with mythavtest -v audio,playback and post the full output
comment:15 by , 15 years ago
Duh! http://code.mythtv.org/trac/changeset/52ac546e3e4db805c8afa3442eac51a9db2b9e8a/
Doesn't have the fix I posted yesterday, it's anterior to http://code.mythtv.org/trac/changeset/9499674e4eec1c6bdde1da12c013e5edd52bb8ed/
comment:16 by , 15 years ago
Thanks, JY.
I am now at e5f39e9, using software mixer and the problem has gone away!
Thanks for all your trouble!
MythVideo is a metadata manager, not a video player. Also, we need a backtrace of your crash.
