  • What does "level" mean in FFprobe output ?

    8 mars 2017, par shintaroid

    I do not understand some attributes in the output by FFprobe

    For a sample file

    $ ffprobe -v error -show_format -show_streams input.mp4
    [STREAM]
    index=0
    codec_name=h264
    codec_long_name=H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
    profile=High
    width=320
    height=240
    has_b_frames=2
    pix_fmt=yuv420p
    level=13                <= This one!
    color_range=N/A

    What does "level" mean here ? Is there any document explain those attributes ?

    11 septembre 2020, par Android198

    I am using FFMPEG since long and using internal file location for inputs its working fine if i build apk with API level 28 but in API level 29 its give error=13 permission denied. I opted out scoped storage by android:requestLegacyExternalStorage="true" in manifest though this error is coming.
