  • 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 :

  • Elimination compression from videos generated from images using ffmpeg ?

    5 novembre 2011, par Magz

    So I'm using ffmpeg to generate videos from a series of images. Unfortunately every video I've generated so far becomes compressed about halfway through (these are about 10-30 second videos). I've tried a lot of different options, but here's an example and the resulting output.

    Any suggestions ?

    ffmpeg -minrate 5000k -maxrate 5000k -bufsize 1835k -b 5000k -s 480x480 \
    
-f image2 -r 10 -i 'dms-%05d.jpeg' output.flv

  • Why menconder fps rate does not work ?

    2 mars 2016, par ACR

    I’m using mencoder to create a video out of some .png files. The problem is that the frame rate doesn’t change, regardless of the -fps flag. The output video has different time lengths (in their properties), but the video’s size and speed are always the same (regardless of the FPS chosen).

    I just want to create a shorted video by using higher FPS rates. In short, a "time-lapse" of my original set of images. What am I doing wrong with mencoder ? I’m using the following command :

    mencoder mf://./IMG/images*.png -mf w=800:h=600:fps=20:type=png -ovc copy -oac copy -o video.avi
