I have both display and mpeg4 encoding working on a DM355 using IPIPE at a resolution of 720x480, but as soon as I try to increase this resolution to 720p (1280x720), my encoded video is distorted/scrambled (as though there is something still expecting 720x480).
The application specifically sets the format to V4L2_STD_MT9T001_720p_30FPS and all widths/heights to 1280x720. I set my bootargs to reflect the new window size (video=davincifb:vid0=1280x720x16,5529K).
With the 720p30 format and the boot args set to the higher resolution, I can still capture at 720x480 without any distortion, but as soon as I try to capture above 720 pixels wide, it all fails. I do not particularly care about display (just capture and mpeg4 encoding to file). I do not have the THS8200 daughter card as referenced by the Sysfs user's guide for HD output, but do I still need it if I don't require HD display? Where might the old resolution still be set?
Thanks! I have been reading these discussions for some tips for the past few weeks and they have been very helpful so far.
