  • How to get bit stream rate of a mpeg Transport Stream ?

    28 septembre 2015, par CompNet

    How can we get the bit rate of a transport stream from the TS source ? One way is to use a constant bitrate while multiplexing the encoded video into TS stream. But how does the variable bitstream work ?

    I found the command with ffmpeg like :

    ffmpeg -i encoded.mp4 -c copy -map 0 -vbsf h264_mp4toannexb mpegts out.ts

    but could not understand the meaning of -vbsf h264_mp4toannexb. Can anyone please explain me how does variable bitrate work ?

    Also, is there any other way we can find the timestamp of each TS packet multiplexed in the Transport Stream ?

    can someone help me what the meaning of this code ? this is a code from ffmpeg remuxing code.

    static void log_packet(const AVFormatContext *fmt_ctx, const AVPacket *pkt, const char *tag, int hours, int mins, int secs, int us, int *time )
    
{
    
    AVRational *time_base = &fmt_ctx->streams[pkt->stream_index]->time_base;
    
    total = total + pkt->duration;
    
  //  printf( "%d:%d:%d.%d \n", hours,  mins,  secs, us );
    
    *time = av_q2d(*time_base) * pkt->pts ;
    
}

  • ffmpeg override the same file for every second of the video [on hold]

    5 février 2017, par Dorin Pleava

    I want to get one image for every 10 seconds from a livestream/video, but the image should have the same name, meaning I want to override it every cycle.

    This is my command :

    ffmpeg.exe -i http://iphone-streaming.ustream.tv/uhls/17074538/streams/live/iphone/playlist.m3u8 -bt 20M -s 480x300 -vf fps=1/10 -y photo.jpg

    This code works for one image but for the next I get this

    "Could not get frame filename number 2 from pattern ’photo.jpg’ (either set updatefirst or use a pattern like %03d within the filename pattern)
    av_interleaved_write_frame() : Invalid argument"

    If I replace photo.jpeg with photo%03d.jpg I get photo001.jpec, followed by photo002.jpeg, etc.
