Re: [Gnash-dev] broadcom crystal hd support

[Jacob Beard]

So, I've had a chance to look into this a bit more, and it seems that 
Gnash via gstreamer does attempt to use the crystalhd hardware. In 
dmesg, I can see the following, which is also printed when watching 
mpeg4 under totem:

[  548.432367] crystalhd 0000:0b:00.0: Opening new user[0] handle

The broadcom drivers proved to be buggy (not a Gnash issue), so I pulled 
from what is supposed to be the most advanced fork of the initial 
broadcom release: http://git.wilsonet.com/crystalhd.git/

This seems to be less buggy with totem, but unfortunately, doesn't work 
with gnash 0.8.8. Youtube, for example, will hang for some time, then 
finally open a the video, play one or two frames and a few seconds of 
audio, and then sometimes display an alert box complaining about gstreamer.

The console output is as follows:

Running DIL (3.21.0) Version
DtsDeviceOpen: Opening HW in mode 0
Scaling command param 0x0,ctx_scal:0x0
ERROR: Couldn't find Method "onYouTubePlayerReady"
<string>Error</string>
ERROR: Couldn't find Method "reportFlashTiming"
<string>Error</string>
gtk-gnash: asobj/NetStream_as.cpp:670: std::auto_ptr<gnash::GnashImage> 
gnash::NetStream_as::decodeNextVideoFrame(): Assertion `! 
_videoDecoder->peek()' failed.

In Megavideo, the console output is similar, but it won't even begin 
playing the video:

Running DIL (3.21.0) Version
DtsDeviceOpen: Opening HW in mode 0
Scaling command param 0x0,ctx_scal:0x0
gtk-gnash: asobj/NetStream_as.cpp:670: std::auto_ptr<gnash::GnashImage> 
gnash::NetStream_as::decodeNextVideoFrame(): Assertion `! 
_videoDecoder->peek()' failed.

Vimeo and the basic flowplayer demo don't seem to render at all: 
http://flowplayer.org/demos/installation/index.html

I'm going to try the latest development version of Gnash, and see if 
that makes a difference. Beyond that, if you have any insight into how I 
could begin to look into debugging this, or if you think I should file 
one or more bug reports, I'd appreciate it if you could let me know.

Thanks!

Jake
