• Convert wmv to mp4 with ffmpeg failing

  10 janvier 2012, par Morph

  I've seen quite a few posts on this, but I can't piece together whether I am doing things right, wrong, or need to download more stuff. I am converting from wmv to mp4 without complaints, but then when I go to play it on the browser window (HTML5) the player just turns grey and blanks out the controls.

  Installing ffmpeg I do

  ./configure --disable-yasm ; make ; make install

  Unless I include the disable yasm it wont go any further. Then I do

  ffmpeg -i myvideo.wmv myvideo.mp4

  All good so far. In my html source I have :

    <video width="320" height="240" controls="controls">
  
    <source src="myvideo.mp4" type="&#39;video/mp4;" codecs="avc1.42E01E, mp4a.40.2"></source>
  
    Your browser does not support the video tag.
  
    </video>

  I am playing this in Chrome 15 and ffmpeg -v is

  ffmpeg version 0.8.6, Copyright (c) 2000-2011 the FFmpeg developers
  
  built on Dec  1 2011 15:42:06 with gcc 4.1.2 20080704 (Red Hat 4.1.2-51)

  libavfilter   2. 23. 0 /  2. 23. 0
  
  libswscale    2.  0. 0 /  2.  0. 0

  So I get the HTML5, click on it to play the movie but then the control bar greys out, leaving the play button, but then the play button cannot be clicked and nothing plays.

  Is there something wrong with what I have done above ? Do I need to download some separate mp4 driver and compile it ? I see people referring to h.264 but I thoughts ffmpeg had that already included...

• ffmpeg determine correct codec to use

  6 janvier 2015, par nha

  I am trying to use .y4m files that I feed into Chrome for playing.
  This is the only format that I can use.

  I have a set of .y4m files that are working for my use case, taken from here.
  For example let’s say that I use the file mobile_qcif_7.5fps.y4m.

  I also have a .mp4 file (specifically the sample small.mp4 file from techslides ). I know how to convert small.mp4 to small.y4m with the following command :

  ffmpeg -y -i small.mp4 small.y4m

  I would like the resulting file to be accepted by Chrome, just like the other file.
  What options should I use (and how to find them) ?

  Additional information

  ffprobe gives :

  Head of the files

  Not sure if this is relevant, but the text content of both files begin like that :

  mobile_qcif_7.5fps.y4m
  
  YUV4MPEG2 W176 H144 F15:2 Ip A128:117

  FRAME

  Additional experiment

  Taking the sample mobile_qcif_7.5fps.y4m, turning it into a .mp4 file and then back into a .y4m produces an invalid file (at least for Chrome).

  Answer to comments in the answer of @SirDarius

  Following the suggestion of @SirDarius ; I tried the following commands.
  They failed to produce a valid file.

  # [COMMAND]   # [RESULT] [HEADER]

  When trying other formats (like yuv420p12be, which was in the output of -pix_fmts), I had the following output (hence my previous trials) :

  $  ffmpeg -i small.mp4 -vf fps=7.5 -an -c:v rawvideo -f yuv4mpegpipe -pix_fmt yuv420p12be -y small_yuv420p12be.y4m

  Could not write header for output file #0 (incorrect codec parameters ?): Input/output error

  After that, I also tried to edit with an hexadecimal editor (bless) the small_yuv420p.y4m file. I replace C420mpeg2 by C420, and the file was accepted by Chrome.
  What does the number in 420p[number] correspond to ? It is not explained there.
  Is there any way to make ffmpeg output this kind of header files ?

  @SirDarius, thank you again for your help.

  The question

  (in case you forgot after this text blob)

  How can I convert the small.mp4 into a small.y4m file that has the same properties as the mobile_qcif_7.5fps.y4m file ?

• ffmpeg - Adding audio to a complex filter

  9 janvier 2015, par user3630651

  I am using c# to programmatically write an ffmpeg command to crossfade a logo into a video. I also need to cut a couple of seconds into the video.

  Here is the currently working ffmpeg command :
  (No audio)

  I want to add audio from "video.mp4"([1:a]) to the output starting a few seconds in, how do I go about this without causing a buffer overflow ?

  Thank you for your help in advance !
