  • How to mix two PCM streams into single mp4 file ?

    28 mars 2012, par newentry

    How to merge two PCM streams into single mp4 file format. One of the PCM is obtained from MIC source i.e person A's voice and on the other hand i receive person B's voice which is finally decoded to PCM.The goal is to mix the two PCM and play the audio smoothly.It is like a call recording but the approach is different. And also is it possible using ffmpeg ?

  • Errors when streaming h264 video from gstreamer to ffmpeg

    14 juin 2016, par Michael Ng

    Hi I am trying to receive a udp/rtp stream with ffmpeg in the client side but is having trouble.

    Server side pipeline :

     gst-launch-1.0 -v filesrc location=video2.mp4 ! decodebin ! x264enc  !
    
 rtph264pay ! udpsink host=127.0.0.1 port=5006

    On the client side, I can play the video with the following pipeline :

    gst-launch-1.0 -e udpsrc uri=udp://0.0.0.0:5006 ! application/x-rtp, clock-rate=90000, payload=96 ! rtph264depay ! decodebin ! autovideosink

    However, since I want to convert the stream into a rtsp/http stream, I tried to receive the rtp stream with ffmpeg and perform something like :

    ffmpeg -i udp://127.0.0.1:5006 -acodec copy -vcodec copy http://localhost:8090/feed1.ffm

    But before doing that, I was testing this approach by saving the stream into a mp4 file with :

    ffmpeg -f h264 -i udp://127.0.0.1:5006 -strict -2 -f mp4 stream.mp4

    But this did not work, it gave me the following error :

    missing picture in access unit with size 15019525 [h264 @ 0x11d5100]
    no frame ! [h264 @ 0x11f06c0] decoding for stream 0 failed [h264 @
    0x11f06c0] Could not find codec parameters for stream 0 (Video : h264) :
    unspecified size Consider increasing the value for the
    ’analyzeduration’ and ’probesize’ options [h264 @ 0x11f06c0]
    Estimating duration from bitrate, this may be inaccurate
    udp ://127.0.0.1:5006 : could not find codec parameters

    Have anyone tried such approach before or experienced similar problem, I would like to get some direction on how to solve it. Thanks !

  • Pass ffmpeg Stream to OpenCV

    29 avril 2021, par Georg

    I would like to use the redirection operator to bring the stream from ffmpeg to cv2 so that I can recognize or mark the faces on the stream and redirect this stream again so that it runs under another stream.

    


    One withoutfacedetect and One withfacedetect.

    


    raspivid -w 1920 -h 1080 -fps 30 -o - -t 0 -vf -hf -b 6000000 | ffmpeg -f h264 -i - -vcodec copy -g 50 -strict experimental -f tee -map 0:v "[f=flv]rtmp://xx.xx.xx.xx/live/withoutfacedetect |[f=h264]pipe:1" > test.mp4


    


    I then read up on CV2 and came across the article.

    


    https://www.bogotobogo.com/python/OpenCV_Python/python_opencv3_Image_Object_Detection_Face_Detection_Haar_Cascade_Classifiers.php

    


    I then ran the script with my picture and was very amazed that there was a square around my face.

    


    But now back to business. What is the best way to do this ?

    


    thanks to @Mark Setchell, forgot to mention that I'm using a Raspberry Pi 4.
