Description

Description: Hang on some example files
Version: latest trunk (via git)
URL: see attached

Steps that will reproduce the problem?
ffmpeg -y -i sample.mpg sample.m4v

What is the expected result?
Converted file or error message.

What happens instead?
ffmpeg hangs - ctrl+c doesn't kill the process.

Possible workaround:
-

Any additional information:

  • Example: (see next comment)
  • Command: ffmpeg -y -i sample.mpg sample.m4v

Is this also reproducible without external libraries?

(And please explain how you manage to produce a version number that looks 3000 versions old.)

comment:2 in reply to: ↑ 1 Changed 5 years ago by Alex__

Is this also reproducible without external libraries?

Can you provide me some more information on what you need exactly? E.g. the following command doesn't hang: "ffmpeg -i sample.mpg -vcodec copy -acodec copy sample-out.mpg".

(And please explain how you manage to produce a version number that looks 3000 versions old.)

Compiling latest trunk:

(I suspect you are wrong: FFmpeg does not hang for the sample.)

Try any command line that does not involve an external library, often ffmpeg -i input -qscale 2 out.avi / out.mpg

comment:4 in reply to: ↑ 3 Changed 5 years ago by Alex__

(I suspect you are wrong: FFmpeg does not hang for the sample.)

Let put is this way: it does not hang for the sample on your system . It does on my (OS X 10.7.1, compiler arguments as shown above with the given example):

Btw: the file "out.avi" has a size of 109MB. See "muxing overhead 106233.836009%" and "Stream #0.0[0x1e0]: Video: mpeg1video...104857 kb/s...". Might be related.

Replying to cehoyos:

(I suspect you are wrong: FFmpeg does not hang for the sample.)

Just double checked with a fresh Ubuntu 11.04 installation and ffmpeg + x264 compiled from trunk. Ffmpeg definitely hangs using the above mentioned compile/command parameters and the given example file.

Input sample-issue-488.mpg seems to hang for me on Arch Linux x86_64 and Ubuntu 11.04 32-bit.
