I convert .mov file created by Canon to H.264, container mp4 - QuickTime(?) ffprobe give me: [format] format_name=mov,mp4,m4a,3gp,3g2,mj2 format_long_name=QuickTime / MOV start_time=0.045000 duration=7.808000 size=954931
video stream [streams.stream.0] codec_name=h264 codec_time_base=1/180000 time_base=1/90000 start_pts=5940 start_time=0.066000 duration_ts=702702 duration=7.807800 bit_rate=810598 nb_frames=234 audio [streams.stream.1] codec_name=aac codec_time_base=1/48000 time_base=1/48000 start_pts=2160 start_time=0.045000 duration_ts=372736 duration=7.765333 After converting it to h264: [format] start_time=-0.033333 duration=7.842000 size=889221 bit_rate=907136 [streams.stream.0] r_frame_rate=30000/1001 avg_frame_rate=30000/1001 time_base=1/30000 start_pts=0 start_time=0.000000 duration_ts=235235 duration=7.841167 [streams.stream.1] time_base=1/48000 start_pts=-1600 start_time=-0.033333 duration_ts=374336 duration=7.798667 Why start_time is not zero? In second movie, audio begins before or after start movie? In first - both video and audio start_time is non zero, what it means? _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
