  • ffmpeg play raw h264 stream, dts/pts problem

    29 mars 2019, par LoganMia

    I need to use ffmpeg to play the raw h264 stream, but there is no dts/pts inside, there is a timestamp

    void h264_decode(void *h264_buffer, int buflen, double timestamp) {
    
    ...
    
    AVStream * st = ic->streams[pkt->stream_index]; //video stream
    
    double duration_s = av_q2d(st->time_base);
    
    double duration = duration_s / av_q2d(st->time_base);
    
    pkt_ts = pkt->dts = pkt->pts = frame_index * duration; // no B frame
    
    ...
    
 }

    But the playback speed is too slow,
    How can I use timestamp to set pts/dts correctly ?
    Thanks .

  • How play audio from a .mkv file from specific frame in python

    31 juillet 2022, par ChaseRatliff

    I would like to know how I could go about playing audio from a .mkv file. I am trying to play video. I am using opencv to display the video and ffpyplayer to play the audio. I can set the frame I want to start playing at in opencv but not in ffplayer. Any ideas or suggestions would help a ton. Here is what I have came up with.

    


    import cv2
from ffpyplayer.player import MediaPlayer

video_path=videoName

def PlayVideo(video_path):
    font = cv2.FONT_HERSHEY_SIMPLEX
    video=cv2.VideoCapture(video_path)

    video.set(cv2.CAP_PROP_POS_FRAMES, 7200)
    player = MediaPlayer(video_path)
    while True:
        font = cv2.FONT_HERSHEY_SIMPLEX
        grabbed, frame=video.read()
        audio_frame, val = player.get_frame()

    if not grabbed:
        print("End of video")
        break
        
    if cv2.waitKey(28) & 0xFF == ord("q"):
        break

    cv2.imshow("Video", frame)
    if val != 'eof' and audio_frame is not None:
        #audio
        img, t = audio_frame

video.release()
cv2.destroyAllWindows()

PlayVideo(video_path)
