[17:27] <Compnn> intel bought realvideo huh
[17:31] <Daemon404> yeah
[17:31] <Daemon404> lol
[17:31] <Daemon404> perhaps they are trying to get a stronger market in china
[17:31] <Daemon404> <_<
[17:35] <Compnn> well
[17:35] <Compnn> rmvb hwdecode on phones/netbooks 
[17:35] <Compnn> to win the chipwar in china :)
[17:49] <Daemon404> lol
[17:54] <Compn> so how long until these companies band together to destroy software patents
[17:54] <Compn> or software patents destroys all of these companies ?
[17:54] <Compn> i think it could go either way
[18:00] <Daemon404> no
[18:00] <Daemon404> they band together
[18:00] <Daemon404> to form one giant patent troll
[18:03] <Compn> and we watch rmvb since theres no reason to have new codecs ?
[18:12] <Daemon404> indeed

[18:59] <Nagy|2> how is it that avfilter_get_video_buffer is considered thread-safe in ffplay (i.e. thread_safe_callbacks == 1)? Looking at the code, the entire pool based stuff doesn't seem thread-safe?
[20:17] <michaelni> Nagy|2, the calls to get_buffer() should be under a mutex
[20:17] <michaelni> see pthread.c
[20:18] <Nagy|2> why set thread_safe_callbacks = 1?
[20:19] <michaelni> its faster
[20:19] <michaelni> it says that get_buffer() can be called from a different thread
[20:19] <michaelni> not from multiple at the same time
[20:19] <Nagy|2> ah!
[20:20] <Nagy|2> thread_safe_callbacks seems rather misleading to me

[20:22] <michaelni> Nagy|2, yes the name isnt very well choosen but its public API so not easy to fix and even less so when we try to stay compatible with forks
[20:24] <Nagy|2> michaelni: understood, I would like to suggest to add "can be called synchronously from another thread" or something to the doc.
[20:25] <Nagy|2> right now it just says "an be called  from another thread", which is a bit open to misinterpretion
[20:26] <michaelni> iam happy to apply such a patch if you post one ...
[20:26] <michaelni> one that adds such text ...
[20:27] <Nagy|2> will do
