  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • What does profile means in an aac encoded audio

    22 avril 2020, par Ananta Prodhan

    I am trying to concat two video files with ffmpeg concat demuxer for most of the part it works just fine !
But when I try to concat videos which has two different audio profile with same codec, it concats with the resulting video having weird sound problem. And when re-encoding the resulting video it will spit out a lots of error related to audio.

    



    Here is ffprobe output for some audio stream from different video files
Video 1

    



    [STREAM]
index=1
codec_name=aac
codec_long_name=unknown
profile=4
codec_type=audio
codec_time_base=1/48000
codec_tag_string=[0][0][0][0]
codec_tag=0x0000
sample_fmt=fltp
...
[/STREAM]


    



    Video 2

    



    [STREAM]
index=1
codec_name=aac
codec_long_name=unknown
profile=1
codec_type=audio
codec_time_base=1/48000
codec_tag_string=[0][0][0][0]
codec_tag=0x0000
sample_fmt=fltp
...
[/STREAM]


    



    Video 3

    



    [STREAM]
index=1
codec_name=aac
codec_long_name=unknown
profile=28
codec_type=audio
codec_time_base=1/48000
codec_tag_string=[0][0][0][0]
codec_tag=0x0000
sample_fmt=fltp
...
[/STREAM]


    



    Look the different profile= values.I was able to reproduce 28 and 1 but was failed for 4

    



    28 = he_aac_v2 1 = ffmpeg default

    



    So what I want to know the most is, 
What does these different values mean for aac ? 
And how to reproduce them with any aac encode ?

    


  • avformat/movenc : add ICC profile support to colr atom

    23 septembre 2019, par vectronic
    avformat/movenc : add ICC profile support to colr atom
    

    If 'write_colr' movflag is set, then movflag 'prefer_icc' can
    be used to first look for an AV_PKT_DATA_ICC_PROFILE entry to
    encode.

    If ICC profile doesn't exist, default behaviour enabled by
    'write_colr' occurs.

  • FFMPEG profile-level-id size is invalid

    18 février 2020, par Mulham Aryan

    I’m trying to record a RTSP streaming from JVC KY-PZ 100.
    So for that i’m using ffmpeg with some parameters like segmentation, hls, ts, m3u8 etc ...
    i’m always getting an error The profile-level-id field size is invalid (41) and Error parsing AU headers

    This is the output of FFPROBE to debug the RTSP
