  • error when converting mts to mp4

    6 janvier 2015, par Chan Kim

    I have many video files that I want to convert to mp4.
    so I installed ffmpeg on my win7 PC (64 bit) which is using shared library.
    I tried to convert an MTS file to MP4 and I get this error.
    What is the problem ?

    EDIT : I thought I solved this problem by using

    ffmpeg -i filename1.mts filename1.mkv

    my Samsung LED TV supports mkv file and during the conversion, it shows

     Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264))
     Stream #0:1 -> #0:1 (ac3 (native) -> vorbis (libvorbis))

    But Alas ! my TV doesn’t support vorbis codec. It only supports mp3, ac3, lpcm, and ADPCM when using mkv container. So the question is : How do people select output audio codec ?

  • I got a green overlay in my video when using multiply blend mode in ffmpeg [on hold]

    30 avril 2014, par GJG

    i´m trying to blend two videos with the multiply blend mode. But I got a green overlay in the resulting video.

    This is a image where are one frame of each input video and one frame of the resulting video
    Composition

    I got this script, this is extracted from a part of my code :

    #!/bin/bash
    ffmpeg -y -i video_top.avi -i video_background.mp4 -filter_complex "blend=all_mode=multiply" -f mp4 -vcodec libx264 out.mp4

    This is the ffmpeg output :

    I don’t know what is wrong, and using others blend modes got others ridiculous results, like having a pink overlay in the video.

    Suggestions will be well appreciated, thanks very much.

  • Decoding h264 in mp4 fragment from IIS Smooth Streaming

    30 novembre 2013, par Julian

    So I've decided to try and make my own client for IIS's Smooth Streaming as a learning exercise and I'm struggling to decode the mp4 fragments.

    I have the following fragment :
    http://www.mediafire.com/download/n32660d920g291c/part+1.mp4

    Which when I try to decode using ffmpeg :

    Consider increasing the value for the 'analyzeduration' and 'probesize' options
    part 1.mp4: could not find codec parameters

    After reading I found the PPS/SPS comes from the CodecPrivateData in the manifest that IIS gives me, which I have as :

    000000016764001eacd940a03da10005161501312d000f162d960000000168ebe3cb22c0

    Binary : http://www.mediafire.com/download/hm3av6h3i1g7ojf/CodecPrivateData

    Which I think is annex b 00000001[SPS]00000001[PPS] but I have no idea what to do with it, I've tried putting it at the beginning of the file but get the same error, I also tried taking just the data in the mdat and sending that to ffmpeg but I get

    [h264 @ 0000000001da8a80] sps_id out of range 0KB sq=    0B f=0/0
    [h264 @ 0000000001da8a80] non-existing PPS referenced

    Consider increasing the value for the 'analyzeduration' and 'probesize' options
    part 1 - Copy.mp4: could not find codec parameters

    So I then tried putting the CodecPrivateData just before the mdat section and I then get this

    [h264 @ 0000000001d38a80] sps_id out of range 0KB sq=    0B f=0/0

    part 1 - Copy.mp4: could not find codec parameters

    I seem to be missing something to get this to decode and I'm just not sure what so I'm hoping someone knowledgeable with h264 can help me out ! Ultimately I want to get this working in DirectShow but even getting it to work in ffmpeg would be a massive help !
