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
or wherever is easiest for you

also probably -demuxer lavf wont crash...

I have uploaded a short capture file (using wget) to the incoming directory as

'-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.

comment:5 Changed 13 years ago by 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?

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.

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