  • Fuji .mov file converted by ffmpeg doesn't play in Windows Media Player [closed]

    30 août 2023, par glipster

    My Fuji X-T3 generates an FHD movie as a .mov with HEVC video and PPM audio. The new Media Player on Windows won't play this (without buying a codec) so I convert it to .mp4 using ffmpeg CLI (ffmpeg -i in.mov out.mp4). The resulting .mp4 file uses AVC video and AAC LC audio. This plays fine in VLC, but will not play in Windows Media Player nor Media Player. I've experimented with various options, but nothing seems to work.
For the original source .mov file, MediaInfo identifies 3 streams :
1stVid : English, 201Mb/s, 1920*1080 (16:9), at 29.970 FPS, HEVC (Main10@L5.2@High)
1stAud : english, 2304 kb/s, 48.0 hKz, 24 bits, 2 channels,PCM (Little/Signed)
1 : QuickTime TC

    


    The Output .mp4 file shows :
1stVid : English 3312kb/s, 1920*1080 (16:9) at 29.970 FPS, AVC (High 10@L4)(CABAC/4 RefFrames)
1stAud : English 132 kb/s, 48.0 kHz, 2 channels, AC LC
1 : QuickTime TC

    


    Using ffmpeg CLI, I tried changing the bitrates for the video and audio, I tried removing the timecode stream, tried a different AAC codec, tried moving the metadata to the front (-movflags faststart), also tried -strict experimental, tried first converting to .mkv (which does work) and then converting to .mp4 (with and without copy). I had hoped one of these might work ; but nothing has worked thus far.

    


    Has anyone else solved this problem ? Any help would be greatly appreciated.

    


  • vf_colorspace : don’t enable passthrough if bitdepth doesn’t match.

    vf_colorspace : don’t enable passthrough if bitdepth doesn’t match.
    

    Also check return value of av_frame_copy() in passthrough mode, so that
    if a copy fails (as it did here, because bitdepth didn’t match), the filter
    doesn’t return success, which would mean sending an uninitialized framebuffer
    further down the filtergraph.

  • Don't work some keys of coding in FFmpeg

    <?
       // $videoPath — path to the video file
       // $newVideoPath — path of the resultant video file

       exec('/usr/bin/ffmpeg -i ' . $videoPath .

    I defined keys which don’t work :
    - dct8x8 1 - partitions +parti4x4+parti8x8+partp4x4+partp8x8+partb8x8 (coding of video doesn’t work)
    - me_method full (the video file is coded, but it isn’t started in a player)
    FFmpeg version : 1.2.6

    How to involve an adaptive method of transformations 8x8 in an I-shot and to set a method of an assessment of the movement of full pixel as full ?
