Segfault on a valid WMV3 video file with DMO (windows binary) video codec

[t.artem@…]

ffplay 0.7.0 plays it just fine.

When I delete win32 binary codecs mplayer plays it just fine.

Assigning to Reimar, but I suspect this is WONTFIX, we cannot change DLLs.

I cannot disagree, but mplayer at least could probably try a built in codec (which actually works fine).

[reimar]

Some clarifications:
First, MPlayer can and does patch binary codecs actually, at runtime.
Secondly, the native decoder still has some issues, it does not support some beta-version formats or interlacing.
Overall, the assumption is that if a binary codec is provided, users want it to be used and have made sure they got a working version.
It would be somewhat interesting to know what binary codec you used, where you got it from and why it crashed (does it crash only with that file?).
But in the end I do think that the current behaviour is mostly as intended really...

My binary codec was download years ago from mplayerhq website (included in the win32 binary codecs official package).

If you'd like, I can upload the codec files somewhere.

It plays other WMV files without any problems.

[compn]

did you try the other wmv3 decoders?

iirc there is -vc wmvdmo and -vc wmv9dmo
but like everyone says, if binary crashes there isnt much we can do.

Like I've already mentioned, the built-in WMV decoder handles this file just fine. So maybe you have to adjust priority of codecs for MPlayer so that built-in open source decoders are always tried first.

[compn]

i was just curious if the other dmo decoder worked on it.
mplayer -vc wmvdmo sample.wmv
mplayer -vc wmv9dmo sample.wmv

the problem is that when the binary codec crashes, it crashes mplayer as well, since mplayer doesnt start a new thread to use the decoder.

thus, it cant fallback to the native decoder when it crashes.
i vote for putting native decoders above priority of binary decoders.

maybe if the ffwmv3 decoder detected interlaced frames and would quit so the binary codec could give it a try.

actually, do we even have wmv3 interlaced samples?
does wmv3 interlaced exist?

[compn]

oops, there is wmv3 interlaced, nevermind.

Now that WMV3/WMV9 is supported natively, I guess we can close this bug report.
