  avutil : Fix linking x86 asm constants with Clang in MSVC mode
  This fixes building with Clang in MSVC mode, for x86, which was
  
  broken in 6e49b8699657b808b7dc80033f2c3f2d0e029fa3 (in Nov 2024) ;
  
  previously it failed with undefined symbols for the constants
  
  defined with DECLARE_ASM_CONST, accessed via inline assembly.
  Before 57861911a34e1c33796be97f2b2f44e05fffd647, there was an
  
      #elif defined(__GNUC__) || defined(__clang__)
  
  case before the
  
      #elif defined(_MSC_VER)
  
  case for defining DECLARE_ASM_CONST, which included av_used.
  
  (This case included the explicit "defined(__clang__)" since
  
  f637046d3134a331e4b5a7243ac3dfb92735b8a5.)
  After 57861911a34e1c33796be97f2b2f44e05fffd647, it used the
  
  generic definition of DECLARE_ASM_CONST that also included
  
  av_used - which also worked for Clang in MSVC mode. But after
  
  6e49b8699657b808b7dc80033f2c3f2d0e029fa3, Clang in MSVC mode
  
  ended up using the MSVC specific variant which lacked the
  
  av_used declaration, causing linker errors due to undefined
  
  symbols.

• 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;

  


  This is the output of ffprobe :

  it seems to me that all codec informations are present :

  


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


  


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

  


  Thank you
