  • Disconnect Network Xcode app crash

    15 novembre 2013, par Igor Malasevschi

    I am using ffmpeg library for publishing Video and Audio Live Streaming to the rtmp server.
    I work under MacOS (in Xcode), for capturing I use Qtkit framework.

    As example i consulted the open source app QTFFmpeg : https://github.com/BigHillSoftware/QTFFmpeg

    The main issue is : while i disconnect network cable application crash.
    For encode and stream i use AVFormatСontext.

    Callback for video is :

     -(void)captureOutput:(QTCaptureOutput*)captureOutput  didOutputVideoFrame:(CVImageBufferRef)videoFrame
    
withSampleBuffer:(QTSampleBuffer*)sampleBuffer   fromConnection:(QTCaptureConnection*)connection
    

    

    

    
returnval  = av_interleaved_write_frame(avFormatContext, &avPacket);
    
if (returnVal != 0)
    
  { Never Happens   !!!! }

    Started debug and application crahs on :0 mach_msg_trap.

    Please help me to solve the issue.
    IF you are able to download the source and try to debug without network will be very good.

    Thank You,
    Igor

  • Reducing the Frame-Rate of a Network Video Stream with FFMPEG

    2 juillet 2013, par Adi Shavit

    I have a network video stream that I am decoding with the ffmpeg C library.
    I'd like to reduce the maximal frame rate to some maximum, say 15 fps.
    I used the filter fps=fps=15, but even on a 25 fps video stream this caused frame duplication. I presume this was due to network delays.

    Is there some way to reduce the maximal frame-rate but avoid frame duplication and just get delays instead ?
    If not, is there a way to identify if a decoded frame is one of the duplicates ?

  • Why is merging of two network streams in ffmpeg raising RTP errors ?

    13 février 2019, par KOMsandFriends

    I want to take the video stream from network stream A, while taking the audio stream from network stream B.

    I tried the command :

    ffmpeg -i rtsp://192.168.1.1 -i http://192.168.1.2 -c copy -map 0:v:0 -map 1:a:0 -f mp4 out.mp4

    Which continuously raises the following errors :

    [rtsp @ 0x564b44779f60] max delay reached. need to consume packet
    
[rtsp @ 0x564b44779f60] RTP: missed 591 packets

    While the commands

    ffmpeg -i rtsp://192.168.1.1 -c copy -f mp4 out.mp4

    and

    ffmpeg -i http://192.168.1.2 -c copy -f mp3 out.mp3

    work without problems.

    The video stream is HEVC, the audio stream is MP3. What am I missing ?
