I've run into an intermittent problem with playing x264-encoded files that use bpyramid. If I seek around a whole bunch, eventually mplayer crashes. It displays lots of messages like these:

The manual page says bpyramid is experimental ;-) Anyway, the test I did with it, worked fine, at least with mplayer, I didn't check ffplay. Hmm. Did you copy-and-paste the test command I posted? Did you try it a couple times? Nope, sorry, I cannot put any time & effort in this, I have my own h264-related problems ;-)

Well, thanks for checking. I just don't want anybody to read this thread and think the problems I'm having are isolated and unreproducible -- I'm pretty sure they should be easy to verify. It usually takes about one minute of running the command I provided before any problems occur; just opening the file and seeking a few times is almost certainly not going to be sufficient.

IIRC this issue has been reported more often, and also IIRC some work has been done it and it should occur less, but it seems it still occurs every now and then.

That doesn't help you of course :-( Sorry for babbling.

No problem; if anybody else has a moment, though, I would appreciate a bit of testing and confirmation. Once again:

while true ; do echo seek (((((((((RANDOM-16200) / 500)) sleep 0.5 done |
mplayer pyramid.avi -slave

Thanks, Corey
