You can't supply two input formats "-f" to one input. ffmpeg is using
the second one.
tps@t420:~/AMC/test$ v4l2-ctl --device=/dev/video1 --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
Index : 0
Type : Video Capture
Pixel Format: 'MPEG' (compressed)
Name : MPEG2-TS with AVC/AAC streams
Can you dump the capabilities of the device? (I use v4l-info for that.)
IIUC it needs to have the capabilities VIDEO_CAPTURE and STREAMING to
be supported by ffmpeg. (I don't know anything about Linux's hdpvr
device driver.)
