dheitmueller/cx23885_fixes.git and mygica x8507

[Alfredo Jesús Delaiti]

Hi all

I tried the patches made ​​by Devin Heitmueller, and returned soundto 
the plate mygica X8507.
Has not corrected the green band that appears on the left side and 
shrinks the image by changing a little the aspect ratio, compresses a 
bit horizontally. With kernel versions 3.0, 3.1 and 3.2 that did not happen.

Thanks

Alfredo

Hello Alfredo,

Thanks for testing.  Glad to hear you're having some success with
those patches.  A few questions about your specific board (since I
don't have the actual hardware):

1.  Which cx2388x based chip does it have?  cx23885?  cx23887?  cx23888?
2.  Specifically which video standard are you using?  NTSC?  PAL-BG?  PAL-DK?
3.  What input are you capturing on?  Tuner?  Composite?  S-video?
4.  Can you provide a screenshot showing the problem?
5.  Are you capturing raw video, or using MPEG encoder (assuming your
board has a cx23417)?

My guess is this is some sort of problem with the video standard
selection.  All of my testing thus far has been with NTSC-M, so I
would guess there is probably some general regression in PAL or SECAM
support (which should be pretty easy to fix once I have the answers to
the above questions).

CX23885

PAL-Nc and NTSC (ntsc is fine at 765 pixels)

Tuner

Yes, but read below

Raw video, not have a cx23417

The problem was that tvtime was set to 768, by passing a resolution to 
720 was solved. Sorry for not having tried before.
With a resolution of 720 pixels the image looks good.
My sincere apologies and thanks.

I'll have to check if that's a driver bug or not.  The way the logic
is supposed to work is the application is supposed to propose a size,
and if the driver concludes the size is unacceptable it should return
the size that it intends to actually operate at.  The application is
expected to read the resulting size from the driver and adjust
accordingly.

Hence, either:

1.  the driver is saying "ok" to 768 and then tvtime receives green
video from the driver.
2.  the driver properly returns 720 when asked for 768, but tvtime
doesn't check for the adjusted size.

Scenario #1 is a driver bug, and scenario #2 is a tvtime bug.

What I can I do to know what is the problem?

I tried the following:

I have two cards, one FlyVideo 3000 that has no problems with TVTime to 
change the resolution (no green line on the right side) and over the 
X8507 has the problem.

With the X8507 card with the resolution set at 768 pixels, if I change 
the TV standards NTSC, PAL-M, PAL-N, NTSC-JP no green line(Of course the 
image is distorted). If change to Pal, Pal-Nc and Pal-60 shows the green 
line. Always using TVTime.

Output of TVTime at 768 first and 720 below
