#70 joining mpgs fails with 64-bit off_t

[Anonymous]

I've never managed to successfully join a set of mpg
files together, always getting the dreaded "failed,
range results in an empty chunk" error regardless of
range I used.

Building a debugging version of mpgtx shows what the
problem is:
Now processing vid-01.mpg 1/5...
new Chunk: from:0xffffffff00000000, to:0x4c9004

The chunk->from is being initialised to '-1' in
chunkTab.cxx, but this doesn't sign-extend to 64 bits.

Casting it to (off_t) doesn't appear to work, but
setting it to 0 does. I've attached a patch.

This should solve Bug ID 863345 (which has been open
nearly 2 years !:-)

Hi Anonymous!

I could not reproduce your reported bug, so please give me
additional info.
What does "64-bit off_t" mean?
Building with LFS? This is what Makefile usualy do.
What is special on your case?
What OS on which architecture do you use.
How did you build mpgtx?
How did you invoke it and what exactly is the output?

Your patch fixes only this issue, but break other things.
A better solution should be found.

Kindly regards,
Erik
