• ffmpeg split video not working with starting with 0 second [closed]

  9 mars 2013, par SmitShah

  I got one issue regarding splitting video which is starting from 0th second say 0 to 15 second. I had seen many post and i followed syntax of them.

  e.g

  ffmpeg -ss 00:00:00 -t 00:00:15 -i 'Wildlife.wmv' '1.wmv'

  or

  ffmpeg -i 'Wildlife.wmv' -ss 00:00:00 -t 00:00:15 '1.wmv'

  or

  ffmpeg -ss 00:00:00 -i 'Wildlife.wmv' -t 00:00:15 '1.wmv'

  none of above syntax is able to split video from begging of time to 15 seconds of video.

  can anyone help me with this ,actually i'm new with ffmpeg. ffmpeg version information

  ffmpeg-php version string: 0.6.0-svn ffmpeg-php build date string: Mar 7 2013 16:54:24 libavcodec build number: 3426306 libavcodec version number: 3426306

• ios http live black screen

  11 mars 2013, par jagsler

  In my ios app I am trying to play videos using http live streaming. The playing goes well until I decide to use the scrubber and skip to some point that hasn't buffered yet. From that moment the audio goes on but the videos goes black.

  I've converted my .MP4 videos with the following command :

  avconv -y -i video.mp4 -f mpegts -acodec libmp3lame -ar 48000 -ab 64k -s 640x480 -vcodec libx264 -b 64k -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -subq 7 -trellis 0 -refs 0 -coder 0 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -bt 200k -maxrate 64k -bufsize 64k -rc_eq 'blurCplx^(1-qComp)' -qcomp 0.6 -qmin 30 -qmax 51 -qdiff 4 -level 30 -aspect 640:480 -g 30 -async 2 sample_64.ts

  I did this with multiple bitrates (64, 150, 240, 440 and 640) and created one .m3u8 that contains the different streams. After converting I used the mediafilesegmenter to split the video in segments of each 10 seconds.

  After scrubbing the following appears in the output window :

  The code for my videoplayer :

  self.streamPlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
  
  [self.view addSubview:self.streamPlayer.view];
  
  [self.streamPlayer setFullscreen:YES animated:YES];

  This problem does not occur when skipping to a point that has already been buffered.
