Xv doesn't work

[dsd]

openchrome doesn't enable Xv on VX855. When you enable it with the attached patch, it is easy to make the system crash:

"gst-launch videotestsrc ! xvimagesink" opens up the gstreamer window as expected, it gets painted fully green, then the system immediately hangs. I can SSH in but the display is totally frozen. Not even killing X unfreezes the display.

2 new log messages appear in Xorg.0.log at the point of hang:

Freed 0 (pool 0) Freed 0 (pool 0)

With os33, I experience the exact symptoms described by #9407. [With os32, mplayer/vlc did not hang the system.] When running mplayer, my bypass on os33 is to tell mplayer to use the 'x11' driver -- then I do not get the system hang (but the picture is smaller than I like).

Log. (It's normal for os34, except for the two 'Freed 0 (pool 0)' lines at the end)

Jon Nettleton reports that Xv is working on his local codebase but is not yet stable enough for distribution. He'll hopefully post an early version to the devel list for testing soon.

cjb will package the new openchrome from #10061 and when he has done so he will set this ticket to 'test in build.'

Replying to cjb:

test in os113

My criterion is how well the XO-1.5 plays "movies". With kernel-2.6.31_xo1.5-20100312.1740.1.olpc.bca5e9d.i586 installed in os112, 'Mplayer' plays movies as well as they are played on an XO-1. On that kernel, 'VLC' also plays movies for me on XO-1.5.

It would be useful for you to check that this is also the case in os113.

Tested in os113:

• "gst-launch videotestsrc ! xvimagesink" worked fine,
• "mplayer tv://" worked fine, though there was a periodic motion pause,
• "mplayer file.ts", where file.ts was a half hour DVB-T filtered transport stream of a television broadcast at 25 fps 720x576 MPEG2 9500 kbps, worked fine.

Tested in os117, still works. Closing.
