  • Change file format from flv to anything android will play

    19 octobre 2011, par Bilthon

    I need to take this file which encoded is in h264 but in a flv container and just put it in a mp4, 3gp or whatever file format the android MediaPlayer will understand.

    I want to do this natively. As I will not be decoding nor encoding anything I think I will not be wasting a lot of power (am I wrong ?)

    I followed the instructions from here http://www.roman10.net/?p=394 and could sucessfully compile and use ffmpeg and use it with mp4 and 3gp files.

    But when it comes to flv files it fails. I understand there is no format definition for flv files in that specific port of ffmpeg for android.

    There is no libavformat/flv.h header file for instance.

    Maybe that's why this works :

    extern AVInputFormat ff_mov_demuxer ;
    av_register_input_format(&ff_mov_demuxer) ;

    While this fails :

    extern AVInputFormat ff_flv_demuxer;
    
av_register_input_format(&ff_flv_demuxer);

    Question is, is there a light at the end of the tunnel ? has someone done something similar ? is it useful ? I mean, I can always just throw the flv media file into a flash player and voila.. the thing is that this would be a parcial solution, as it will not work for all those folks running slower devices that can't yet run Flash.

    Nelson

    PS. Just in case. Here's some info about the file I'm talking about :

    ffmpeg -i rio.flv

    Skip mode search based on reference frame consistency

    This commit enables the encoder to skip NEARMV and ZEROMV if the
    above and left blocks have identical reference frame, and the
    current reference is different from that. It reduces the runtime
    of speed 3 for test sequences :
    bus cif at 1000 kbps 10064 ms -> 9823 ms
    pedestrian 1080p at 2000 kbps 193078 ms -> 189559 ms

    The compression performance is changed by
    derf -0.085%
    stdhd -0.103%
