  • ffmpeg and streaming video - frame time issue

    6 mai 2014, par 4ntoine

    I’ve compiled ffmpeg-android (https://github.com/appunite/AndroidFFmpeg) and it works for files.
    The problem is that it shows nothing for network streams (both rtmp and hls) as frame timestamp is too big and it seems to be not from video beginning (as for file). Then it waits for the first frame time which for network stream is too big :

    also i can’t figure out what timestamp for frame for network stream means (for file frames it’s a time from video beginning)

    for file it’s clear : time_base is frame number and timestamp is time from video beginning and it plays the files :

    So what is the meaning of timestamp for stream and what should i change to make it playing streams (rtmp/hls - its can be opened now but it wait for frame time which is far in the future) ?

    UPDATE :

        int64_t pts = av_frame_get_best_effort_timestamp(frame);
    
if (pts == AV_NOPTS_VALUE) {
    
    pts = 0;
    
}
    
int64_t time = av_rescale_q(pts, stream->time_base, AV_TIME_BASE_Q);
    
LOGI(10,
    
        "player_decode_video Decoded video frame: %f, time_base: %" SCNd64,
    
        time/1000000.0, pts);
    
player_wait_for_frame(player, time, stream_no);

    it extracts time which is far in future :

    player_wait_for_frame[0 = Video] = (568.233000) - (0.000977)

    Is it correct ?
