Some videos are not played correctly if ffmpeg is compiled with --disable-asm

[Honza]

Summary of the bug:

Some videos (multiple different ones) are not played correctly (video looks corrupted or black) in mplayer if ffmpeg is compiled with --disable-asm. Those videos can be played correctly with ffplay, vlc or gst-play. At least in one case it generates nice error messages. When ffmpeg is compiled normally, mplayer plays video normally.

I suspect the bug is actually in ffmpeg, but as I'm not able to reproduce it in ffmpeg directly ...

How to reproduce:

Patches should be submitted to the mplayer-dev-eng mailing list and not this bug tracker.

Beginning of the problematic video (more that enough to see the problem).

[Honza]

Forgot to mention: the "Error while decoding frame!" are not present when the video plays correctly.

[reimar]

I tried with --target=generic for MPlayer which should have the same effect.
But the issue is not reproducible with the latest version and included FFmpeg at least.
1.2.1 is the special release for old FFmpeg versions, so it would be a good idea to try a newer version of both MPlayer and FFmpeg.
That it's not reproducible with FFmpeg unfortunately doesn't mean much as FFmpeg doesn't really use the custom get_buffer MPlayer uses.
Might also want to try -nodr.

[Honza]

Not sure what you mean with --target=generic. I'm using Gentoo, 1.2.1 is the last stable mplayer there and it's using external ffmpeg - can the problem be related to that? (Actually, isn't the fact it uses external ffmpeg included in the verbose output, along with configure flags for both ffmpeg and mplayer?)

What version of ffmpeg is considered old?

-nodr makes no difference.

I suppose that I want to use the version with asm anyway, as it's going to be considerably faster. But I'm surprised noone else is having same problem. If it's really the same issue as the first problematic video, it happened on two computers (although similarly configured) over multiple mplayer, ffmpeg and compiler versions. (I didn't really cared because the first video was not important, but the last one might be.)
