  • ffmpeg how to calculate complete frame ['I' frame ] from [ 'P' frame ]. It is conceptually correct?

    15 February 2014, by Whoami

    I am trying to get the knowledge of ffmpeg streaming video handling.

    what I understood:

    I get from the IPed Camaera, the frames like 'IPPPPPPPPPPPPPPPPIPPPPPPP'..

    Frame 'I' is a complete frame, where as frame 'P' depends on the previous either 'P' or 'I' frame which ever is the closes.

    I get the frame by using avcodec_decode_video2

    while (av_read_frame (context, &packet) >=0)
    
{   
    
        //LOGD (" Received PACKET...DTS and PTS  %ld and %ld ", packet.pts, packet.dts);
    

    
        if(packet.stream_index == videoStreamIndex ) { 
    
                avcodec_decode_video2 (pCodecCtx, pFrame, &finished, &packet);
    
                if ( finished) {
    
                // Here is my frame, getting the type by av_get_picture_type_char(pFrame->pict_type).
    
          }
    
 }

    Now, When i display just the frames that i have received, looks like whenever 'I' frame received, it displays properly, when received 'P' frames, the image goes for a toss.

    1) We need to manually do any calculation to convert 'P' Frame to 'I' Frame so that it can be rendered?

    2) If not (1), what do i have to take care?..Does DTS/PTS calcuation do the magic here ?

  • avcodec/liblc3enc: don't force unspec channel layouts

    avcodec/liblc3enc: don't force unspec channel layouts

    We only care about channel count. Layout details will be ignored either way.

  • How do I end a pipe?

    5 September 2019, by Leo

    I have trouble using ffprobe from node.js. I need the audio lengths MP3 files. There is an npm package, get-audio-duration for this.

    The package calls ffprobe through an execa command. It works well for .flac files both when when using a filename and a stream. However for .mp3 files it fails for streams.

    I suspected some problems with execa so I checked from the command line (on Windows 10):

    type file.mp3 | ffprobe -

    (Where I left out the parameters to ffprobe for clarity.)

    This kind of works, but says duration=N/A.

    It looks to me like ffprobe didn’t get the info that the input is finished. Or, it dint care about it. (There is a 4 year old bug report about this on the ffmpeg issue site which was closed for no obvious reason.)

    Is it possible to somehow tell ffprobe that the pipe has ended?
