  • 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.

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

  • FFMpeg generating screenshots drop frames

    6 octobre 2011, par Morgan

    I'm using FFMpeg to extract frames from a video file, and for most videos it works flawlessly. But certain videos it seems to have to seek to the position that I want to take the screenshot from, and drops all the frames on the way there taking quite a while if the position i'm generating a screenshot from is near the end of the video. Here is the command I'm using to extract my screenshot.

    ffmpeg -ss 60 -i input.mkv -vframes 1 -f image2 -an -r 1/5 output.jpg

    and the output I receive
