Hello all, I’ve been tinkering around with the
encode H264 demos, and I was wondering if there was a way in V4L2 to find out
if any frames were dropped on the input side? I’ve been looking at using VIDIOC_G_PERF with ioctl, but that’s not
supported anymore, So after the CLEAR(v4l2buf); v4l2buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE; v4l2buf.memory = V4L2_MEMORY_MMAP; /* Get a frame buffer with captured data */ if (ioctl(inputFd, VIDIOC_DQBUF, &v4l2buf) ==
-1) { if (errno == EAGAIN) { continue; } ERR("VIDIOC_DQBUF failed (%s)\n",
strerror(errno)); breakLoop(THREAD_FAILURE); } Call, I tried printing out v4l2buf.timestamp, or the v4l2buf.timecode.tvsecs,
v4l2buf.sequence and all show 0! Is there a way around this or a solution to my problem? Thank you |
