    but the fps is too low, it always has 3 5 fps, the user view is not good.
    how can i do to change the fps.
    this is my jni code with ffmpeg init.

  • Syncronising Video/audio with two different sources

    22 mai 2016, par Indy

    I have an issue with an very old film that I’m trying to recover. I have two source of the same film.

    Source 1 (from ffmeg -i) :

    Duration: 02:43:35.77, start: 0.000000, bitrate: 1342 kb/s
    
Stream #0:0: Video: mpeg4 (Simple Profile) (DIVX / 0x58564944), yuv420p, 720x480 [SAR 1:1 DAR 3:2], 1200 kb/s, 29.97 fps, 29.97 tbr, 29.97 tbn, 30k tbc
    
Stream #0:1: Audio: mp3 (U[0][0][0] / 0x0055), 48000 Hz, stereo, s16p, 128 kb/s

    Source 2 (from ffmeg -i) :

    Duration: 02:46:11.04, start: 0.000000, bitrate: 1625 kb/s
    
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1200x720 [SAR 1:1 DAR 5:3], 1431 kb/s, 30 fps, 30 tbr, 30 tbn, 60 tbc (default)

    What I would like is to take the audio from source 1 and video from source 2 and create a new file with them.

    I have tried changing the source 1 to 30 fps and then using its audio with source 2’s video but the audio ’fps’ is really after sync after sometime. Perhaps my approach is wrong.

    what’s the best way to take the audio from source 1 synced with source 2’s video ?

    Any help is appreciated. Thanks,
    Indy
