  • Fragmented MP4 has wrong duration in Windows Media Player

    3 février 2020, par Expressingx

    I’m streaming video from a camera to a file using ffmpeg. The case to use Fragmented MP4 is that there can be sudden power off and lose the video. I’ve configured the fragments to be at least 30 secs and this is how much the Windows Media Player reports for the duration even if its 2 hours long, after that it keeps streaming the video but is not seekable after the 30th second. How can be that fixed ?

    ffmpeg -c copy -movflags frag_keyframe+separate_moof+omit_tfhd_offset -min_frag_duration 30000000 -bsf:a aac_adtstoasc \ out.mp4

    If I use -movflags frag_keyframe+empty_moov then the video is not seekable at all and no duration reported.

    I aim for seekable video with correct duration both on VLC/Windows Media Player

  • libaomenc : Add support for tiles

    libaomenc : Add support for tiles

    Adds an option to specify the number of tile rows and columns, then uses
    
a uniform tiling if possible and otherwise a fixed tiling with equal-sized
    
tiles to fill the frame.
    

    Also adds -tile-columns and -tile-rows options to make tilings with
    
power-of-two numbers of tiles, matching the behaviour of the libvpx/VP9
    
encoder.

  • exporting ogg videos from video slideshow (mp4) and audio (wav) using ffmpeg in python

    17 septembre 2018, par jtz

    I have tried to find a solution already, but just cannot make it work. I want to export an .ogg-video by combining a video slideshow (mp4) with an audio file (wav) by using ffmpeg in python. The audio is shorter than the video and should have an offset of 2000 milliseconds, so that it starts approximately in the middle of the video. The code that I tried is essentially this :

    subprocess.call(’ffmpeg.exe -itsoffset 0 -i slideshows/slideshow.mp4 -itsoffset 2000 -i sounds/audio.wav -codec:v libtheora -codec:a libvorbis output.ogg’, shell= True)

    FYI : I need to create a couple of different video formats from the video and audio input, so substituting the ogg with a different format is no option. I have already successfully created .mp4-video-files and .webm-video-files from the material, but need the .ogg in addition. Also, Power Point does not like any of the exported videos, maybe this might be relevant for finding the problem here (I also unsuccessfully tried to fix this issue).
