it is still a problem with 23279

[compn]

can you save some of your asf file (with wget or other program) and see if it still crashes?

if it does still crash, upload it to ​ftp://upload.mplayerhq.hu/MPlayer/incoming
or wherever is easiest for you

also probably -demuxer lavf wont crash...

[warren.sturm@…]

errors out of -demuxer lavf

[warren.sturm@…]

I have uploaded a short capture file (using wget) to the incoming directory as
bugzilla-821-video.asf.

'-demuxer lavf' did not crash but there was some other spew which is attached

(In reply to comment #3)

It seems that the upload did not work. failed to create file.

[warren.sturm@…]

It looks like r23322 no longer crashes but just emits errors like the ones in the attachment. Is -demuxer lavf now the default?

[reimar]

You only uploaded the first 10kB of the file which is not enough. You have to use a different file name to try again, since overwriting files in incoming is not allowed.

[warren.sturm@…]

ok. The file should be uploaded as bug821-2.asf.

i get a crash sometimes on your sample
but cant reproduce it in gdb :(
