• 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 :

  C:\>ffplay.exe -f h264 -vcodec h264 -g 52 "part 1.mp4"

  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

  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

  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 !

• 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.

• 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 ?

  Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

  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 ?
