  • How to record playable video files in gstreamer even if recording is interrupted unexpectedly (e.g. power disconnects) ?

    16 septembre 2021, par Otter_warrior

    I have been recording video streams on my Jetson Xavier NX using a simple gstreamer pipeline such as this

    


    gst-launch-1.0 -v \
nvarguscamerasrc sensor-id=0 ! \
'video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)NV12, framerate=(fraction)30/1' ! \
nvv4l2h265enc ! 'video/x-h265, stream-format=(string)byte-stream' ! \
h265parse ! qtmux ! filesink location=video.mp4 -e


    


    All is working if the recording is interrupted by keyboard interrupt Ctrl + C, but if the recording is interrupted unexpectedly (e.g. power gets disconnected) the resulting file has no playable stream, even if the file size is correct.

    


    I know that mp4 recording needs to be stopped properly otherwise it won't have the necessary information at the end of the file, but I was wondering if there was any other gstreamer pipelines or final file formats that would allow for an H265 encoded video file to be playable even if the recording is ended unexpectedly.

    


    It would be good even if the recorded file needed to be converted before being playable (e.g. with ffmpeg), as long as the information can be recovered without having to go through non-free mp4 recovery tools.

  • UAC compliant webcams (mic) Access under Android in general and under FFMPEG for Android

    21 décembre 2012, par user1545779

    The traditional way to access a UAC compliant webcam mic has always been :
    ffmpeg -f alsa -i plughw:CARD=U0x46d0x821,DEV=0
    under Android versions upto and including version 4.0 However as we all know, alsa implementation is one of the most problematic areas in sound implementation on Android.

    Has there been any changes in recent versions of Android as to how to access the builtin mic in a UAC complaint webcam or for that matter a USB mic
