  • FFMPEG HLS multiple Tracks not in sync

    2 juin 2020, par LordFenixNC

    This script works but the video doesnt sync with the sub or audio tracks. Could someone help fix this or Help me with a NEW script. I have been trying to figure this out with 0 luck and have had friends look at it. I even went to FFMPEG discord and FB asking for help from others who have posted scripts in the past. Seems no one has a interest in this. Please will someone help me.

    



    All I am trying to do is BULK encode MKVs to HLS with multiple resoutions in 10 sec segments and include all the Audio and SUb tracks that were originally in the MKV

  • avutil/timecode : fix av_timecode_get_smpte_from_framenum with 50/60 fps

    20 juillet 2020, par Marton Balint
    avutil/timecode : fix av_timecode_get_smpte_from_framenum with 50/60 fps

    SMPTE 12M timecode can only count frames up to 39, because the tens-of-frames
    
value is stored in 2 bit. In order to resolve this 50/60 fps SMPTE timecode is
    
using the field bit (which is the same bit as the phase correction bit) to
    
signal the least significant bit of a 50/60 fps timecode. See SMPTE ST
    
12-1:2014 section 12.1.
    

    Therefore we slightly change the format of the return value of
    
av_timecode_get_smpte_from_framenum and AV_FRAME_DATA_S12M_TIMECODE and start
    
using the previously unused Phase Correction bit as Field bit. (As the SMPTE
    
standard suggests)
    

    We add 50/60 fps support to av_timecode_get_smpte_from_framenum by calling the
    
recently added av_timecode_get_smpte function in it which already handles this
    
properly.
    

    This change affects the decklink indev and the DV and MXF muxers. MXF has no
    
fate test for 50/60fps content, DV does, therefore the changes.
    

    MediaInfo (a recent version) confirms that half-frame timecode must be inserted
    
to DV. MXFInspect confirms valid timecode insertion to the System Item of MXF
    
files. For MXF, also see EBU R122.
    

    Note that for DV the field flag is not used because in the HDV specs (SMPTE
    
370M) it is still defined as biphase mark polarity correction flag. So it
    
should not matter that the DV muxer overrides the field bit.
