Hello -
I have a saa7134 video encoder card "RTD Embedded Technologies VFG73"
in 2.6.28.9 with recent v4l2 (3919b17dc88e). It has two compression
channels and no tuner.
The output pixel format for the compressed devices is showing
'BGR3' and it should be 'MPEG'. The data from the output
device appears to be uncompressed data.
Also, the video standard has been disconnected from the input device.
The input device /dev/video1 is NTSC, and the encoded
output device /dev/video3 is PAL. They should both be NTSC. H.Verkuil
had initially fixed this problem last April.
I'm wondering if I missed something obvious or missed changes in the
last 6 months
or if there could be a regression problem.
Thanks for your help.
