  • video playing sample on iPhone using libffmpeg

    6 mai 2014, par deimus

    can someone please provide a reference or an example on usage of libffmpeg library for playing video files not supported by apple.

    Let consider mkv file.
    I suppose the library decodes and passes the raw media data to AVFoundation objects to play it on device. Am I right ?

  • how to play H264 mpegts in iphone

    26 décembre 2012, par jAckOdE

    My server encode video files (h264/acc, mpegts based format) by ffmpeg, and send to a client in a iPhonse. The default mediaplayer of ios sdk can not play those videos. How to play H264/mpegts in Ios ? Is there any opensource player for ios that can play h264/mpeg-ts file.

    Thanks.

  • Converting any video to iPhone - transcoding logic/algorithm ?

    28 septembre 2012, par cajwine

    I have many-many video files in different formats (mostly avi). For example, some relevant lines from ffprobe :

      Duration: 02:27:14.70, start: 0.000000, bitrate: 664 kb/s
    
    Stream #0.0: Video: mpeg4, yuv420p, 608x256 [PAR 1:1 DAR 19:8], 23.98 tbr, 23.98 tbn, 23.98 tbc
    
    Stream #0.1: Audio: mp3, 44100 Hz, stereo, s16, 96 kb/s
    

    
  Duration: 00:20:51.84, start: 0.000000, bitrate: 3286 kb/s
    
    Stream #0.0: Video: mpeg4, yuv420p, 640x480 [PAR 1:1 DAR 4:3], 25 tbr, 25 tbn, 25 tbc
    
    Stream #0.1: Audio: mp3, 48000 Hz, stereo, s16, 128 kb/s
    

    
  Duration: 01:26:01.84, start: 0.000000, bitrate: 845 kb/s
    
    Stream #0.0: Video: mpeg4, yuv420p, 704x544 [PAR 1:1 DAR 22:17], 25 fps, 25 tbr, 25 tbn, 30k tbc
    
    Stream #0.1: Audio: mp3, 44100 Hz, stereo, s16, 128 kb/s
    

    
  Duration: 01:42:25.68, start: 0.000000, bitrate: 952 kb/s
    
    Stream #0.0: Video: h264 (High), yuv420p, 600x244 [PAR 1:1 DAR 150:61], 25 fps, 25 tbr, 25 tbn, 50 tbc

    As you can see, the bitrates, video-sizes, codecs are vary. Want write a script (bash, perl) what will convert them for iPhone with ffmpeg.

    With googling i found many different ffmpeg profiles, but all profiles are "static", e.g. converts video to same resolution and this is probably not the right way, because i have many different video resolutions with many different bitrates. (this applies for the audio too).

    I'm able write the script - but need help with one basic question.

    I need help with the algorithm how to calculate the values for ffmpeg arguments from the above ffprobe results. E.g. when have video 704x544 and 845kb/s and another video with smaller size 640x480 but 3200kb/s bitrate - how to calculate the "right values" for ffmpeg in the script ?

    What is right algorithm/logic for transcoding video for the desired device ? (in my case iPhone)

    If someone care, I have ffmpeg recompiled with "nonfree" codecs, and have mencoder (from mplayer package) too.

    Second : In the avi containers are many videos already in the mpeg4 format. How to determine the "fastest" converting profile ? Mean a profile, where ffmpeg will only do the less-possible calculations, so probably will leave as-is : the format mpeg4, the size, the bitrate and "only" will change the container format. Is this possible ?

    I was read many ffmpeg SO questions, but not find answers - maybe I missed something. Can somebody point me to some good documents ?
