Description

When trying out MythArchive? from the 0.20 release, and attempting to master and burn a DVD, the process failed at the mythreplex stage. When I manually re-ran the exact mythreplex command it used, I found that it segfaulted:

mythtv@myth:~$ mythreplex --demux  --fix_sync -o /mythtv/mytharchive//work/1/stream -v 224 -a 192 "/mythtv/mytharchive//work/1/newfile.mpg"

I first tried getting a backtrace of the exact binary I ran (despite the lack of debug symbols) as a quick check; however, it seems to suggest stack corruption:

#0  0x0805264b in pes_id_out ()
#1  0xffffffff in ?? ()
#2  0x00000000 in ?? ()

I then rebuilt mythreplex with debug symbols, and obtained the following backtrace:

Can you provide a small sample file for download that you know doesn't work?

Here's a .mpg file with VBI that doesn't work for me.

The bug is in mythtv-0.20/programs/mythtranscode/replex/element.c

Function get_audio_info calls find_audio_sync. The second arg is an array of 4 bytes. Almost the first thing that find_audio_sync does is clear the first 7 bytes -- oops.

I don't know what the correct code is, but it is clear that this is the cause of the crash.

BTW, a gdb backtrace shows about 85 recusive calls to get_pes(). I expect that this is accurate (but I may be wrong). This seems very wasteful since the recursive call in get_pes is a last-action call and could be turned into iteration very easily. Is there a reason not to do this?

[I just posted a message like this to mythtv-users@… . There are several reports of this crash on that list and on atrpms]

(In [11294]) Possible fix for #2420. find_audio_sync() was always expecting the buf array passed as a parameter to be 7 bytes but some of the calling functions where only creating 4 and 6 byte arrays.

Also spotted another possible bug where the new fix sync stuff could try to write to the output files before they were opened.

Not sure if it fixes the seg fault or the other reported problems with stack smashing because I couldn't reproduce it even with the sample file provided.

Refs. #2420

Was confirmed fixed on the dev list, AFAICT.

(In [11365]) Merge [11294] from trunk - Seems to fix the segfault and stack smashing errors - at least no one has reported otherwise. References #2420.

I can confirm that the committed change fixes the problem I observed. mythreplex now works here, and as a result MythArchive? now works perfectly for me; thanks for the fix!

Replying to paulh:

I can re-create the segfault in the fixes branch. Looking at the core file it looks again like a crazy recursion and/or smashed stack. There are some fixes at the trunk that did not get merged down. I merged the mythtranscode\replex changes from trunk and the problem is fixed at least for my recording. I can supply it if anyone still wants to look at it, tho i'll have to cut it down, as it's currently a 4 hr recording.

I'll reopen the ticket, and attach the patch from the merge from trunk. Feel free to re-close if noone cares about the fixes branch.
