  • how to synchronize video with audio through pts in ffmpeg

    10 décembre 2011, par Michael Chen

    I play a h264 format video with ffmpeg, and I try to synchronize video with audio by pts.
    the video format information :

     Metadata:
    
    major_brand     : isom
    
    minor_version   : 512
    
    compatible_brands: mp41
    
    creation_time   : 1970-01-01 00:00:00
    
  Duration: 00:00:11.72, start: 0.000000, bitrate: 300 kb/s
    
    Stream #0:0(eng): Video: h264 (Main) (avc1 / 0x31637661), yuv420p, 512x384, 250 kb/s, 25 fps, 25 tbr, 25025 tbn, 50 tbc
    
    Metadata:
    
      creation_time   : 1970-01-01 00:00:00
    
      handler_name    : VideoHandler
    
    Stream #0:1(eng): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, s16, 44 kb/s
    
    Metadata:
    
      creation_time   : 1970-01-01 00:00:00
    
      handler_name    : SoundHandler

    but the first frame's pts is 0 and the second frame' pts is 1001, base_time * pts = 11s ! why ?
    there are long time between the 1st frame with the 2nd frame !

  • ffmpeg settings for converting to mp4 and ogg for HTML5 video [closed]

    18 août 2012, par betamax

    Despite all the hype, in reality the HTML5 video tag has a bit of a problem. In order to use it and for it to be cross browser compatible, you have to include more than one format of the video. To target all supported browsers these formats are mp4 and ogg.

    I was searching around for optimum settings for each format but unfortunately I couldn't find any. I'm using ffmpeg 0.6 which has the tagline "Works with HTML5". I'm no video expert so I was wondering if anyone could recommend decent settings for each format ?

  • ffmpeg watermarking error : video pixel format unknown, Parser not found for codec

    13 décembre 2011, par Sunil

    I am trying to watermark my video but I am getting pixel format and codec errors.

    I am using latest version of FFmpeg git-7d531e8 64-bit Static (Latest) (2011-12-12) from link http://ffmpeg.zeranoe.com/builds/

    I am using the below code to add watermark to my video.

    ffmpeg -i inputputfile.avi -target pal-vcd "movie=abc.png [Watermark] ; [in][Watermark] overlay=10:10 [out]" outputfile.avi.

    But i am receiving the error of video pixel format unknown and parser not found for codec error.

    Later, I changed by code to add codec and pixel format.

    ffmpeg -i inputputfile.avi -vcodec wmv3 -pxl_fmt yuv420p -target pal-vcd "movie=abc.png [Watermark] ; [in][Watermark] overlay=10:10 [out]" outputfile.avi.

    However I am still receiving the same error. Please help.
