Error message at end of asf stream

[Yossi]

This ticket continues https://ffmpeg.org/trac/ffmpeg/ticket/588 which was fixed but now when i'm running fmpeg on the full sized video (not only the first 10MB sample), it crashes around frame 1989 with message: get_buffer() failed
I am using the static 64-bit Build from zeranoe @ 2012-01-27 (​http://ffmpeg.zeranoe.com/builds/win64/static/ffmpeg-git-01fcbdf-win64-static.7z).
You can reproduce the problem by running ffmpeg directly on the video file as it's stored on our web site, i.e.:

ffmpeg.exe -i ​http://media.webcollage.net/rwvfp/wc/cp/3493374/module/instantupdatetest/_cp/products/1318977439061/tab-da6bd996-030a-4d8d-b4a7-105c57117116/resource-3c1aaa56-90fd-4fb5-9383-e0606761a4ca.wmv -y bad-video.wmv

Please add backtrace etc. as explained on ​http://ffmpeg.org/bugreports.html

ffmpeg does not crash it just aborts decoding video.

Is there something that plays more of this file or better ?
Or is the problem just that an error message is shown ?

[Carl Eugen Hoyos]

The only problem I see is that instead of finishing silently (as done with other samples) both ffmpeg and ffplay show an error on exit which is unexpected (assuming this is a valid file).

Replying to michael:

I just downloaded a newer build of ffmpeg of ​http://ffmpeg.zeranoe.com/builds/win64/static/ffmpeg-20130302-git-4f0d4ac-win64-static.7z and retried it: it seems like the movie is transcoded to the end (or at least very very close to it) and the resulting movie is playable, however ffmpeg finishes the transcoding with the following output to the console:

Stream mapping:

Stream #0:1 -> #0:0 (wmv2 -> msmpeg4)

Stream #0:0 -> #0:1 (wmav2 -> wmav2)

get_buffer() failed q=31.0 size= 8810kB time=00:01:19.60 bitrate= 906.7kbits/s dup=85 drop=0

Error while decoding stream #0:0: Error number -22 occurred

frame= 1990 fps= 18 q=31.0 Lsize= 8892kB time=00:01:19.97 bitrate= 910.8kbits/s dup=85 drop=0

video:7351kB audio:1249kB subtitle:0 global headers:0kB muxing overhead 3.396760%

which is causing problems to our software that runs ffmpeg since it scans the stdout for errors and finds one.
BTW, playing the original movie with VLC v2.0.4
