Hello, i'm trying to record a video using FFmpegFrameGrabber.

FFmpegLogCallback.set();
grabber = new FFmpegFrameGrabber("/dev/video0");
grabber.setOption("input_format","h264");
grabber.setPixelFormat(avutil.AV_PIX_FMT_YUV420P);

In my console i have

Error: [video4linux2,v4l2 @ 0x86cc39c0] Cannot find a proper format for codec 'h264' (id 28), pixel format 'none' (id -1)

Error: Assertion *codec_id != AV_CODEC_ID_NONE failed at libavdevice/v4l2.c:811

I'm sure that my Logitech C920 has h264 input format
Because when i call "v4l2-ctl --list-formats-ext" in Linux console it outputs

ioctl: VIDIOC_ENUM_FMT

So i have to simply evaluate the follow FFmpeg command via JavaCV:
ffmpeg -c:v h264 -i /dev/video0 -c:v copy /mnt/cifs/TestVideos/default[10].mp4

How do i do that?

Thanks a lot!

We need a setVideoCodec() or setVideoCodecName(). @fcinfo has start working on this in pull #948, but unfortunately, tests fail so I cannot merge this. If you could help be finishing what he started, that would be great!

There is no setVideoCodecName() method in FFmpegFrameGrabber class and setVideoCodec() doesn't work for me.
Thanks anyway, i'll try to use mjpeg codec
