Hello, I tried to make an .mkv format video recording with audio using the following command on the AGX Xavier dev kit
gst-launch-1.0 v4l2src device=/dev/video0 ! 'video/x-raw, width=3840, height=2160, framerate=30/1, format=UYVY' ! nvvidconv ! 'video/x-raw(memory:NVMM), format=I420, format=(string)I420, width=(int)3840,height=(int)2160' ! queue ! omxh264enc bitrate=32000000 ! h264parse ! matroskamux name=mux ! filesink location=file1.mkv -e alsasrc device="hw:1,1" ! 'audio/x-raw, format=(string)S16LE, layout=(string)interleaved, channels (int)2, channel-mask=(bitmask)0x0000000000000003, rate=(int)48000' ! queue ! audioconvert ! lamemp3enc ! mux.
There is video, but NO audio . However, there is a static noise in the background.
The working command I use for audio saving is
gst-launch-1.0 alsasrc num-buffers=1000 device="hw:1,1" ! audio/x-raw,format=S16LE ! wavenc ! filesink location = a.wav
The working command I use for video saving
gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw, format=(string)UYVY, width=(int)3840, height=(int)2160" ! nvvidconv ! "video/x-raw(memory:NVMM), format=(string)I420, width=(int)3840, height=(int)2160" ! omxh264enc ! matroskamux ! queue ! filesink location=<filename1.mkv>
So I would like to combine these commands for on-device saving.
Could someone give me the correct command for saving video and audio together in an unique file through the use of Gstreamer?
The output file from filesink can be .mp4, .ogg, .mkv, or whatever as long as the video has audio with it.
Thank you!
