GStreamer i.MX6 Encoding

Audio, from a file	gst-launch filesrc location=test.wav ! wavparse ! mfw_mp3encoder ! filesink location=output.mp3
Audio Recording	gst-launch alsasrc num-buffers=$NUMBER blocksize=$SIZE ! mfw_mp3encoder ! filesink location=output.mp3 # where #     duration = $NUMBER*$SIZE*8 / (samplerate *channel *bitwidth) # Example: 60 seconds recording # gst-launch alsasrc num-buffers=240 blocksize=44100 ! mfw_mp3encoder ! filesink location=output.mp3 # # To verify that is correct, do a normal audio playback gst-launch filesrc location=output.mp3 typefind=true ! beepdec ! audioconvert !

Video, from a test source	gst-launch videotestsrc ! queue ! vpuenc ! matroskamux ! filesink location=./test.avi

Video, from Web camera	# when the web cam is connected, the device node /dev/video0 should be present.

Video, from Parallel/MIPI camera	# The camera driver needs to be loaded before executing the pipeline, refer to the BSP document to see which driver to load # MIPI (J5 port): modprobe ov5640_camera_mipi modprobe mxc_v4l2_capture # Parallel (J9 port): modprobe ov5642_camera modprobe mxc_v4l2_capture gst-launch mfw_v4lsrc ! queue ! vpuenc codec=0 ! matroskamux ! filesink location=output.mkv sync=false # Do a 'gst-inspect mfw_v4lsrc' or 'gst-inspect vpuenc' to see other possible settings (resolution, fps, codec, etc.)

Hi,

I'm using boundary device sabreLite and when trying to record video from ov5640 mipi,Its show some error.

command:

gst-launch mfw_v4lsrc ! queue ! vpuenc codec=0 ! matroskamux ! filesink location=output.mkv sync=false

output msg:

But when i include capture-mode

gst-launch mfw_v4lsrc  capture-mode=4 ! queue ! vpuenc codec=0 ! matroskamux ! filesink location=output.mkv sync=false

ls -al

-rwxr-xr-x  1 root root 10476028 Oct 13  2014 output.mkv

When i try to open in vlc, its showing like a image(photo) not a running video.

Please hep me out.

Strange. Do you see the same behavior using gplay to reproduced the recorded video? gplay runs on target.

Is there command for Video/Audio recording? Thank you.
