Comment (by anonymous):

Some additional information which may help: I think this '''may''' have
something to do with IVTV and embedding VBI in the MPEG file. When I
force mytharchive to re-encode, it works fine, but when it attempts to use
the original file, it fails.

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

Comment (by paulh):

(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

Comment (by paulh):

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

Comment (by anonymous):

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!
