• utvideoenc : Enable support for multiple slices and use them

  utvideoenc : Enable support for multiple slices and use them
  The official Ut Video decoder only threads with slices, thus until
  
  now any files encoded by the libavcodec encoder have only been
  
  decodable with a single thread. The default slice count is now
  
  set to subsampled_height / 120.
  Also sets slices to 1 for the Ut Video encoder tests to keep them
  
  green.

• c# NReco.VideoConverter Ubuntu 16.04

  19 septembre 2018, par Neyt Chi

  I’m trying to use the functionality of the NReso library. VideoConverter. The program is launched from Ubuntu OS 16.04 in the MonoDevelopment environment. The operating system is 64 charging. I installed the application FFMpeg and it works fine.
  And I have a problem that does not make a lot of sense. I’m trying to use code NReso.VideoConveter from the site official site https://www.nrecosite.com/video_converter_net.aspx :

  try
  
  {
  
       string [] paths = {"1.mp4",
  
       "1.mp4",
  
       "1.mp4"};
  
       ConcatSettings concatSettings = new ConcatSettings ();
  
       concatSettings.ConcatAudioStream = false;
  
       concatSettings.ConcatVideoStream = true;
  
       FFMpegConverter ffMpegConvert = new FFMpegConverter ();
  
       Console.WriteLine ("Converting ... \ r \ n");
  
       ffMpegConvert.ConcatMedia (paths, "3.mp4", Format.mp4, concatSettings);
  
       Console.WriteLine ("Complete!");
  
  }
  
  catch (Exception e)
  
  {
  
  Console.WriteLine (e.Message);
  
  }

  The code produces an error of type

  "ApplicationName = ’/ home / neytchi / Projects / testVE / testVE /
  bin / Debug / ffmpeg.exe’, CommandLine = ’- y -loglevel info -i
  "1.mp4" -i "1.mp4" -i "1. mp4 "-f mp4 -filter_complex" concat = n = 3 :
  v = 1 [v] "-map" [v] "" 3.mp4 "’, CurrentDirectory =’ / home / neytchi
  / Projects / testVE / testVE / bin / Debug ’, Native error = Access
  denied" or so "Unhandled Exception : Systems
  .ComponentModel.Win32Exception"

  I can not understand the cause of problem, but I’m assuming that the library starts the process as 32-bit, when everything else is 64-bit.
  Any ideas ? Perhaps someone met with a similar on Ubuntu.

• Compiling FFmpeg with option —enable-libass on CentOS 5 32bit [closed]

  26 mai 2012, par whatUwant

  I have already installed libass and libass-devel

  yum install libass libass-devel
  
  ...
  
  Package libass-0.9.11-1.el5.rf.i386 already installed and latest version
  
  Package libass-devel-0.9.11-1.el5.rf.i386 already installed and latest version
  
  Nothing to do

  The source code of ffmpeg is from official git.
  I try to compile ffmpeg with the option —enable-libass. But it prompts "ERROR : libass not found" every time.

  ./configure --enable-version3 \
  
  --enable-libvorbis \
  
  --enable-libx264 \
  
  --enable-libxvid \
  
  --disable-ffplay \
  
  --enable-shared \
  
  --enable-libmp3lame \
  
  --enable-gpl \
  
  --enable-pthreads \
  
  --enable-postproc \
  
  --enable-x11grab \
  
  --enable-libgsm  \
  
  --enable-swscale \
  
  --enable-nonfree \
  
  --enable-avfilter \
  
  --enable-libass

  In config.log it says

  check_pkg_config libass ass/ass.h ass_library_init
  
  ERROR: libass not found

  I've checked

  /usr/local/include/ass/ass.h

  and

  /usr/include/ass/ass.h

  this ass.h does exist in both places.

  "pkg-config —cflags —libs libass" says

  Package enca was not found in the pkg-config search path.
  
  Perhaps you should add the directory containing `enca.pc'
  
  to the PKG_CONFIG_PATH environment variable
  
  Package 'enca', required by 'libass', not found

  "yum install enca" says

  Package enca-1.10-1.el5.rf.i386 already installed and latest version
