• video streaming - mp4 file (x264) - and skip to location

  14 mars 2011, par Raoul

  Previously I was using apache to serve .flv files which an embedded player on an intranet page was playing.

  Is it possible to stream mp4 files (x264 encoded) in a similar manner ? Are there any open source scripts/solutions for doing proper streaming (e.g. people can skip to skip to a part of the video without having to download the parts they've skiped over) ?

  If anyone is doing someting similar I'd love to hear from them

  Thanks

• How to create buffer for video streaming

  4 juin 2014, par John Simpson

  I am developing a Android video player that can play RTSP Stream. I use ffmpeg in jni part to get and decode RTSP Stream. For now, the player can play and then pause video stream. The next step is to create a buffer for the player so that when user pauses video, the player can still load video stream in the next several seconds.

  Is there any good documentation on how to create a buffer for video streaming in proper way ?

  My plan is to create a array of packets. When the array is full, the player calls

   av_read_pause();

  to stop buffering. When the array has spaces, the player will call

   av_read_play();

  to continue buffering. There is a read_thread for getting packets from the buffer and the decode the packets. The read_thread will stop (resume), when user pauses (resume) video.

  Can this plan work ?

• Encoding a video in FFmpeg to X264 and have it playable in Quicktime

  7 mai 2013, par illu

  I am wondering which command line settings i need to explicitly set (or avoid) to make a video encoded into x264 (in the mp4 format) using ffmpeg by default playable in Quicktime. I find that a number of the predefined preset files work for me but some of them won't, for example I can't get any of the lossless ones to work and I'm interested in those ones as well. For example libx264-lossless_max.ffpreset will encode my video but it's only playable in VLC, not in Quicktime. In Quicktime the video stays black. I know Perian is an option but I want my file to be playable without installing Perian. Thanks for your help.
