  • diracdec : fix original Dirac Low Delay profile

    diracdec : fix original Dirac Low Delay profile

    The version structure in the main decoder context was not (and
    
apparently has never been) populated since it was added.
    
Still, having VC-2 break the existing Dirac Low Delay mode was odd and
    
easily avoidable had the specifications authors noticed/cared.

    hevc : set profile based on the profile compatibility flags if needed

    This fixes retrieving a valid profile for many of the FATE conformance samples,
    
allowing them to be properly decoded by the HWAccel after adding a profile check.

  • How to encode audio to AAC with profile FF_PROFILE_AAC_LOW

    18 mai 2016, par alijandro

    I try to encode audio to AAC with profile FF_PROFILE_AAC_LOW by the following settings.

    oc_cxt->profile = FF_PROFILE_AAC_LOW;

    Also from the output of av_dump_format, I got this

    Metadata:
    
encoder         : Lavf57.36.100
    
Stream #0:0: Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 192 kb/s

    But the output is different. Everything is ok, except the output is AAC, not AAC (LC). By using ffprobe to detect, the output information is

    $ ffprobe o.m4a
    
...
    
Stream #0:0(und): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 195 kb/s (default)
    
...

    AAC (LC) is the desired result I need.

    But from the command line, ffmpeg can generate AAC (LC) output. Below is a small test.

    $ ffmpeg -f lavfi -i aevalsrc="sin(440*2*PI*t):d=5" aevalsrc.m4a
    
$ ffprobe aevalsrc.m4a
    
...
    
Stream #0:0(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, mono, fltp, 69 kb/s (default)
    
...

    How can I select FF_PROFILE_LOW to get AAC (LC) output ?
