[CRASH] mythtranscode aborts during a transcode

[david.byui@…]

While running mythtranscode on my fedora 14 backend , it aborts and fails to transcode properly. Backtrace is attached.

Version: Mythtv.i686 0.24-5.fc14

nuvexport @ commit c18508f20448077762d23ab9207c5eb643324dc0

Steps to reproduce:

   nuvexport to Xvid
   myth cutlist [yes]
   enable noise reduction [no]
   enable deinterlacing [yes]
   Crop broadcast overscan border [1.5]
   Audio bitrate [128]
   Variable bitrate video [Yes]
   Multi-pass [no]
   VBR quality/quantisation [6]
   Video bitrate? [768]
   Width? [512]
   Height? [288]

Please attach the output of nuvexport --debug for one of these runs (if run from nuvexport as it seems it is), and also a full backtrace of the issue (all threads).

From the command line in the backtrace you provided here, it looks like you are putting the fifos in /. This is not likely to work unless you are root.

How much memory, and how much swap does this machine have? The backtrace is showing an exception of std::bad_alloc, which is usually thrown when you run out of memory. How often does this occur? With every input file, or just one in particular?

[David Reed <david.byui@…>]

This is a 4 socket Xeon (P4 class) server with 4GB of memory. I've tried to nuvexport about a dozen different videos (with various quality settings), all of which have aborted early with the aforementioned error.

[beirdo]

Please give the output of mythbackend --version so I can look at the correct code while trying to debug this.

Also, if you are ready for upgrading, please try 0.25pre (aka git master branch). A fair amount of bug fixes have been done, which may have fixed this already.

[beirdo]

OK, this is going nowhere fast. If this is still occurring, please reopen with the mythbackend --version output if you'd like this to be worked on. Without knowing which version of the code is broken, I can't do much here.
