asfdemux: scan last packet to determine duration for files saved from broadcasts (6.30 KB, patch)

Description Bastien Nocera 2012-06-21 11:26:00 UTC 
But MPlayer could seek in it.

unseekable ASF stream
Comment 2 Tim-Philipp Müller 2013-03-17 12:32:16 UTC 
That's because it's captured from a broadcast, and the header says it's unseekable too, and of course there's no index either.

We need to calculate the number of packets based on the file size, and then scan to the end to figure out the duration based on the timestamps in the last packets. And then we can hopefully do some basic seeking based on that (or even better, implement seeking by doing a bisect/scan, but first things first).

asfdemux: scan last packet to determine duration for files saved from broadcasts

Tentative patch, should approximate duration hopefully. Only tested with this file though, and not much point trying to implement seeking on a 1.5 second clip..

What should happen with this?

Still valid and patch could be revisited.
