  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Emballe médias : à quoi cela sert ?

  • ffprobe newer version detect audio codec incorrectly

    16 janvier, par alancc

    I find a strange problem.

    


    I have a test video with h264 video codec and aac audio codec. It is at https://drive.google.com/file/d/1YAyz5cO0kb9r0MgahCpISR4bZ_1_n8PL/view?usp=sharing

    


    I build a ffmpeg version by myself, its version is :

    


    ffprobe version 7.0.2 Copyright (c) 2007-2024 the FFmpeg developers
  built with gcc 14.1.0 (Rev3, Built by MSYS2 project)
  configuration: --enable-shared
  libavutil      59.  8.100 / 59.  8.100
  libavcodec     61.  3.100 / 61.  3.100
  libavformat    61.  1.100 / 61.  1.100
  libavdevice    61.  1.100 / 61.  1.100
  libavfilter    10.  1.100 / 10.  1.100
  libswscale      8.  1.100 /  8.  1.100
  libswresample   5.  1.100 /  5.  1.100


    


    I then use ffprobe to get its info :

    


    ffprobe -v quiet -print_format ini -show_streams -show_packets test_h264.mp4 > test_h264.ini


    


    Then I get an ini file which shows the audio codec as MP2 :

    


    [streams.stream.0]
index=0
codec_name=mp2
codec_long_name=MP2 (MPEG audio layer 2)
profile=unknown
codec_type=audio
codec_tag_string=mp4a

max_bit_rate=N/A
bits_per_raw_sample=N/A
nb_frames=378
nb_read_frames=N/A
nb_read_packets=378


    


    Another developer he uses his version of ffprobe :

    


    ffprobe version 2023-02-22-git-d5cc7acff1-full_build-www.gyan.dev Copyright (c) 2007-2023 the FFmpeg developers  


    


    Based on the year, my version(2024) should be newer than his(2023), but his version of ffprobe can get the audio codec properly :

    


    [streams.stream.1]
index=1
codec_name=aac
codec_long_name=AAC (Advanced Audio Coding)
profile=LC
codec_type=audio
codec_tag_string=mp4a
codec_tag=0x6134706d
sample_fmt=fltp
sample_rate=44100
channels=2
channel_layout=stereo
bits_per_sample=0
initial_padding=0
id=0x2
r_frame_rate=0/0
avg_frame_rate=0/0
time_base=1/44100
start_pts=1764
start_time=0.040000

bits_per_raw_sample=N/A
nb_frames=427
nb_read_frames=N/A
nb_read_packets=427
extradata_size=5


    


    Why ?

    


    I also tried a ffprobe version on ubuntu with the following version :

    It will detect the audio as aac properly, but with different parameters, for example, bit_rate is 111733(developer) but 110399(ubuntu). But this parameter comes from the same file so should be the same.

  • FFmpeg wrong codecstring for DASH manifest [closed]

    21 novembre 2024, par Suxsem

    I'm trying to create a DASH stream with ffmpeg with the following command :

    


    ffmpeg -i rtsp://admin:***@camera-retro.lan/ch0_0 ^
       -map 0 ^
       -codec:v copy ^
       -codec:a copy ^
       -f dash ^
       -use_template 1 ^
       -use_timeline 1 ^
       -window_size 50 ^
       -extra_window_size 5 ^
       -seg_duration 5 ^
       tmp/output.mpd


    


    The problem is the generated manifest doesn't contain a valid codecstring for the video part (note the codecs="hev1" part) and thus is not playable by the browser :

    


    &lt;?xml version="1.0" encoding="utf-8"?>&#xA;<mpd xmlns="urn:mpeg:dash:schema:mpd:2011" profiles="urn:mpeg:dash:profile:isoff-live:2011" type="dynamic" minimumupdateperiod="PT6S" suggestedpresentationdelay="PT6S" availabilitystarttime="2024-11-21T12:05:52.604Z" publishtime="2024-11-21T12:05:57.559Z" timeshiftbufferdepth="PT5M1.9S" maxsegmentduration="PT5.0S" minbuffertime="PT12.0S">&#xA;    <programinformation>&#xA;        &#xA;    </programinformation>&#xA;    <servicedescription>&#xA;    </servicedescription>&#xA;    <period start="PT0.0S">&#xA;        <adaptationset contenttype="video" startwithsap="1" segmentalignment="true" bitstreamswitching="true" maxwidth="2304" maxheight="1296" par="16:9">&#xA;            <representation mimetype="video/mp4" codecs="hev1" bandwidth="822093" width="2304" height="1296" scantype="unknown" sar="1:1">&#xA;                <segmenttemplate timescale="90000" initialization="init-stream$RepresentationID$.m4s" media="chunk-stream$RepresentationID$-$Number%05d$.m4s" startnumber="1">&#xA;                    <segmenttimeline>&#xA;                        <s t="0" d="542990"></s>&#xA;                    </segmenttimeline>&#xA;                </segmenttemplate>&#xA;            </representation>&#xA;        </adaptationset>&#xA;        <adaptationset contenttype="audio" startwithsap="1" segmentalignment="true" bitstreamswitching="true">&#xA;            <representation mimetype="audio/mp4" codecs="mp4a.40.2" bandwidth="34143" audiosamplingrate="16000">&#xA;                <audiochannelconfiguration schemeiduri="urn:mpeg:dash:23003:3:audio_channel_configuration:2011" value="1"></audiochannelconfiguration>&#xA;                <segmenttemplate timescale="16000" initialization="init-stream$RepresentationID$.m4s" media="chunk-stream$RepresentationID$-$Number%05d$.m4s" startnumber="1">&#xA;                    <segmenttimeline>&#xA;                        <s t="0" d="81001"></s>&#xA;                    </segmenttimeline>&#xA;                </segmenttemplate>&#xA;            </representation>&#xA;        </adaptationset>&#xA;    </period>&#xA;</mpd>&#xA;

    &#xA;

    This is the output of ffprobe :

    &#xA;

    &#xA;

    it seems to me that all codec informations are present :

    &#xA;

    a=fmtp:96 profile-space=0;profile-id=1;tier-flag=0;level-id=186;interop-constraints=000000000000;&#xA;

    &#xA;

    why ffmpeg is putting only codecs="hev1" instead of the full codecstring (containing the profile, the level and the constraints) ?

    &#xA;

    Thank you
