Hello Ezequiel, Thank you for the notification! My last attempt at implementing V4L API support was about a year ago and it stopped once I realized that there is no userspace which uses that API. FFMPEG and chromium browser had some kind of V4L support, but it all was oriented at downstream driver stacks, and thus, not usable.

Correct, looks like I borrowed that name from the libvdpau API. https://vdpau.pages.freedesktop.org/libvdpau/struct_vdp_picture_info_h264.html#a405f7ef26ea76bb2c446e151062fc001 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
