uvc_stream_start_bandwidth() fails #419

Open skeletoncrewrobotics opened 6 years ago

skeletoncrewrobotics commented 6 years ago

after wrestling with other issues (ndk version, abi list, camera can't do 640x480, styles/themes) I have the apps starting. But no pictures. mostly trying usbCameraTest0 for now. for some reason, MPEG encoding fails, and it falls back to YUV. That seems a bit odd. But it gets to startPreview() and then fails doing a transfer. any ideas?

I have the same problem as well. Any news?

I never got it to work.

I used different cameras, lower bandwidth and 2 cameras worked. Anyone knows how to reduce bandwidth requirements?
