How to write a V4L2 driver to capture MPEG4 / H.263 ?
Hi,
I'm writing a V4L2 driver for a card which capture video in a compressed MPEG4 (H.263+) format. In the VIDIOC_ENUM_FMT, I return the following structure:
const struct v4l2_fmtdesc tsmpeg4_formats[] = {
{
.index = 0,
.type = V4L2_BUF_TYPE_VIDEO_CAPTURE,
.flags = V4L2_FMT_FLAG_COMPRESSED,
.description = "Hardware-encoded MPEG-4",
.pixelformat = V4L2_PIX_FMT_MPEG, }
};
But several applications (GStreamer, VLC) display an error "unknown format 1195724877", and close the dialog. I have the same behavior with the vivi driver.
How do I declare this MPEG4 compressed format in V4L2?
Thanks for your reading,
Dagonux.
