Hello -
I have a RTD Technologies VFG7350 (saa7134 based, two channel, no tuner).
I'd like to stream the compressed data.
I/O read works: v4l2-apps/test/capture-example --device /dev/video2 --read
but streaming does not:
$ v4l2-apps/test/capture-example --device /dev/video2 --mmap/dev/video2 does not support memory mapping: Invalid argument
This is error EINVAL from ioctl( VIDIOC_REQBUFS ).
Streaming is listed as a capability of the device:
$ v4l2-dbg --device /dev/video2 --infoDriver info: Driver name : saa7134 Card type : RTD Embedded Technologies VFG73 Bus info : PCI:0000:02:08.0 Driver version: 526 Capabilities : 0x05000001 Video Capture Read/Write Streaming
Is there hope that streaming can work?
Thank you,Gordon��.n��������+%������w��{.n�����{��g����^n�r������&��z�ޗ�zf���h���~����������_��+v���)ߣ�m
