• how to play m3u8 videos from laravel storage

  10 mars 2019, par Farzane Khazaei

  I used ffmpeg to convert my MP4 videos to M3U8 format to have multiple qualities and stream my videos. because of security reason I have to put my videos in storage folder (not public) and now when I try to watch videos the browser just download M3U8 text file and video wont display. I install chrome extension to display M3U8 videos and i can see my M3U8 videos if I put the files in public folder and call the URL directly. this is my code

  $fileName = $product->details()['sample_file_name'];
  
  $filePath = $product->type.'s/'.$product->id.'/'.$fileName;       
  
  $fileContents = Storage::disk('products')->path($filePath);
  
  $header = ['Content-type' => Storage::disk('products')->mimeType($filePath)];
  
  $header = ['Content-Disposition' => 'attachment; filename='.basename($filePath)];
  
  $response = Response::download($fileContents, $fileName, $header);
  
  return $response;

  please help me what headers should i set for my download response.

• Convert form 30 to 60fps by increasing speed, not duplicating frames. FFmpeg

  14 janvier 2014, par Matt Pellegrini

  I have a video that is incorrectly labelled at 30fps, it is actually 60fps and so looks like it's being played at half speed. The audio is fine, that is, the soundtrack finishes half way through the video clip. I'd like to know how, if possible to fix this, that is double the video speed, making it 60fps and meaning that the audio and video are synced.

  The file is H.264 and the audio MPEG-4 AAC

  Thanks in advance for any help,

  Matt

• libavutil : Hook up the rest of the gcc specific attributes to clang as well

  21 mars 2017, par Martin Storsjö

  libavutil : Hook up the rest of the gcc specific attributes to clang as well
  Hook up all attributes that don’t have a MSVC specific version at the
  
  moment.
  See f637046d313 for details.
  These don’t seem to be critical for building with clang in MSVC mode
  
  though, and thus haven’t been hooked up until now.
  These seem to build fine with as old clang as 3.3 at least.
  
  (clang 3.3 disguises itself as gcc 4.2 normally, so all of these
  
  have been used for clang before, except for av_cold.)
  The clang version numbers themselves are useless for detecting what
  
  attributes are available, since Apple’s clang builds use a completely
  
  different versioning (presenting itself as e.g. clang 8.0 instead
  
  of 3.8).
