• How to suspend ffmpeg file reading ?

  6 décembre 2012, par jAckOdE

  My ffmpeg-based player plays a mpeg-ts file that downloaded from a server. I want my player be able to play the video file even it is being downloaded.

  There is no problem if the download speed is faster than reading speed, otherwise my player crashs. My question is that is there anyway to suspend ffmpeg file reading to wait for data available to proceed?

• Pipe yuv frames to ffmpeg

  6 décembre 2012, par ashrack

  I read camera input frames and then do some transformation on them and then I would like to make a video of it. At the moment I am writing the raw yuv420 images to sdcard as one big file and then invoking staticly compiled FFMPEG to encode it to mp4 movie.

  The problem is because writing 10 images per second results in about 2MB/s of write to SDCARD for an image of 480x320 in yuv420p format. Which is too much for an SDCARD.

  So would it be possible to pipe these yuv420 images directly to FFMPEG and how?

• FFMPEG and H264 encode mp4

  5 décembre 2012, par user1771274

  I tried to encode a video mov to mp4 width h264 codec but I get this error :

  Unknown encoder 'libx264'
  

  But when I check if h264 if supported by my config I saw it does :

  DVD h264 H.264 / AVC / MPG-4 AVC/ MPEG-4 part 10
  

  and my code :

  FFMPEG -y -i video.mov -vcodec h264 video.mp4 ;
  

  Can someone help me with this ? Thanks.
