[MPlayer-users] [PATCH] reworked video capture - testers needed

[Sylvain Petreolle]

Compiles but doesn't work for me (note that it didn't function before
so this  isn't your patch fault).

As reported before mplayer says that the tuner is unable to set the
norm (it supports PAL and SECAM, no problem with xawtv.). Searching in
the ml shows that another person reported it with anoher tv card.

Greetings.
> This patch adds the following features to V4L module:
> 
> - multithreaded audio/video buffering
> - a/v timebase synchronization (sample count vs. gettimeofday)
> - "immediate" mode support for mplayer
> - fixed colorspace stuff - RGB??, YV12 and YUY2 modes now work as
> expected
> - native ALSA9 audio capture
> 
> Please try this patch out. If you're using *BSD, please verify that
> this patch doesn't break anything in bsdbt capture plugin.

> Things you could especially test are 1) trying various colorspaces
> (RGB15|16|24|32, YV12, YUY2, I420) - just to verify that they give

> and 2) capturing a bit longer video (about 2 hours) to verify the a/v
