• Concatenate / Join MP4 files using ffmpeg and windows command line batch NOT LINUX

  17 juillet 2014, par julesverne

  I’ve written a batch script that attempts to take a generic introductory title video (MP4) that runs for 12 seconds and attaches it to the beginning of 4 other MP4 videos (same video but each has a different language audio track)

  According to ffmpeg syntax here : http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20concatenate%20%28join,%20merge%29%20media%20files the concat demuxer needs to be run from a text file that looks like this :

  # this is a comment
  
  file '/path/to/file1'
  
  file '/path/to/file2'
  
  file '/path/to/file3'

  I believe everything in my script up until the point of joining the files appears to be working correctly. But I get this error :

  [concat @ 04177d00] Line 2: unknown keyword ''C:\Users\Joe\1May\session3\readyforfinalconversion\frenchfile.mp4'
  
  filelistFrench.txt: Invalid data found when processing input
  
  [concat @ 03b70a80] Line 2: unknown keyword ''C:\Users\Joe\1May\session3\readyforfinalconversion\spanishfile.mp4'
  
  filelistSpanish.txt: Invalid data found when processing input
  
  [concat @ 0211b960] Line 2: unknown keyword ''C:\Users\Joe\1May\session3\readyforfinalconversion\basquefile.mp4'
  
  filelistBasque.txt: Invalid data found when processing input
  
  [concat @ 03a20a80] Line 2: unknown keyword ''C:\Users\Joe\1May\session3\readyforfinalconversion\Englishfile.mp4'
  
  filelistEnglish.txt: Invalid data found when processing input

  I believe the issue lies in the text file I’m creating. Please excuse my n00b ignorance, but sometimes new script makers like myself get confused about developer jargon and may take things literally.

  So when I look at that example text file they gave, am I correct in thinking THIS is what my text file should look like ?

  # this is a comment
  
  Titlefile.mp4 'C:\Users\Joe\1May\session3\readyforfinalconversion\Titlefile.mp4'
  
  Englishfile.mp4 'C:\Users\Joe\1May\session3\readyforfinalconversion\Englishfile.mp4'

  Again, am I being too literal ? are the quotations correct ? Are the slashes correct ? In the example they provide the slashes in the path are / instead of normal windows \ . I’ll provide the entire script in case it helps.

     set pathtofile[%%i]=%~dp0!language[%%i]!
  
  )
  
  
  
  rem create data file for ffmpeg based on variable data

      echo # this is a comment>>filelist!term[%

      echo file '%pathtotitlevideo%'>>filelist!term[%

      echo file '!pathtofile[%%i]!'>>filelist!term[%

  )
  
  
  
  cls
  
  
  
  rem join files using ffmpeg concat option
  
  
  
  for /L %%i in (1,1,4) do (
  
     c:\ffmpeg\ffmpeg\bin\ffmpeg.exe -loglevel error -f 
  
  
  
  concat -i filelist!term[%%i]!.txt -c copy !language[%
  
  
  
  %i]!.!term[%%i]!.withtitle.mp4
  
  )
  
  
  
  endlocal
  
  
  
  :eof
  
  exit

  EDIT
  Thanks to @foxidrive making me look at the simplicity of it... it occurred to me that Apparently I wasn’t being literal enough. I made these 3 changes and script works perfectly now
  1 : "file" in there example literally meant the word "file"
  2 : needed the use of single quotes not double quotes as it shows in there example.
  3 : Used "\" instead of "/" as they have in there example.

  So NOW my code to create the text files looks like this :

  rem create data file for ffmpeg based on variable data
  
  
  
  for /L %%i in (1,1,4) do (
  
      echo # this is a comment>>filelist!term[%
  
  
  
  %i]!.txt
  
      echo file '%pathtotitlevideo%'>>filelist!term[%
  
  
  
  %i]!.txt
  
      echo file '!pathtofile[%%i]!'>>filelist!term[%
  
  
  
  %i]!.txt
  
  )

  So NOW my text file looks like this :

  # this is a comment    
  
  file 'C:\Users\Joe\1May\session3\readyforfinalconversion\Titlefile.mp4'
  
  file 'C:\Users\Joe\1May\session3\readyforfinalconversion\Englishfile.mp4'

• arm : vp9 : Add NEON itxfm routines

  14 novembre 2016, par Martin Storsjö

  arm : vp9 : Add NEON itxfm routines
  This work is sponsored by, and copyright, Google.
  For the transforms up to 8x8, we can fit all the data (including
  
  temporaries) in registers and just do a straightforward transform
  
  of all the data. For 16x16, we do a transform of 4x16 pixels in
  
  4 slices, using a temporary buffer. For 32x32, we transform 4x32
  
  pixels at a time, in two steps of 4x16 pixels each.
  Examples of relative speedup compared to the C version, from checkasm :
  
                           Cortex       A7     A8     A9    A53
  
  vp9_inv_adst_adst_4x4_add_neon :     3.39   5.83   4.17   4.01
  
  vp9_inv_adst_adst_8x8_add_neon :     3.79   4.86   4.23   3.98
  
  vp9_inv_adst_adst_16x16_add_neon :   3.33   4.36   4.11   4.16
  
  vp9_inv_dct_dct_4x4_add_neon :       4.06   6.16   4.59   4.46
  
  vp9_inv_dct_dct_8x8_add_neon :       4.61   6.01   4.98   4.86
  
  vp9_inv_dct_dct_16x16_add_neon :     3.35   3.44   3.36   3.79
  
  vp9_inv_dct_dct_32x32_add_neon :     3.89   3.50   3.79   4.42
  
  vp9_inv_wht_wht_4x4_add_neon :       3.22   5.13   3.53   3.77
  Thus, the speedup vs C code is around 3-6x.
  This is mostly marginally faster than the corresponding routines
  
  in libvpx on most cores, tested with their 32x32 idct (compared to
  
  vpx_idct32x32_1024_add_neon). These numbers are slightly in libvpx’s
  
  favour since their version doesn’t clear the input buffer like ours
  
  do (although the effect of that on the total runtime probably is
  
  negligible.)
                             Cortex       A7       A8       A9      A53
  
  vp9_inv_dct_dct_32x32_add_neon :    18436.8  16874.1  14235.1  11988.9
  
  libvpx vpx_idct32x32_1024_add_neon 20789.0  13344.3  15049.9  13030.5
  Only on the Cortex A8, the libvpx function is faster. On the other cores,
  
  ours is slightly faster even though ours has got source block clearing
  
  integrated.
  This is an adapted cherry-pick from libav commits
  
  a67ae67083151f2f9595a1f2d17b601da19b939e and
  
  52d196fb30fb6628921b5f1b31e7bd11eb7e1d9a.
