Hi.
I’m trying to capture from webcam to file.
My webcam records image by MJPEG, so I have to convert from MJPEG to H.264 for disk space.
The software conversion of MJPEG to H264 works correctly, but the hardware conversion does not.
After various attempts, I could finally reproduce it with the following command.
$ sudo mpi_dec_test -w 800 -h 600 -t 8 -i mjpeg.mjpg -o mjpeg.yuv -d -1

H.264 hardware decoder works correctly.
I’d be happy if you’d help me.
Thank you.
