  • Webcam streaming from Mac using FFmpeg

    22 juillet 2016, par Galaxy

    I want to stream my webcam from Mac using FFmpeg.

    First I checked the supported devices using ffmpeg -f avfoundation -list_devices true -i ""

    Output :

    [AVFoundation input device @ 0x7fdf1bd03000] AVFoundation video devices:
    
[AVFoundation input device @ 0x7fdf1bd03000] [0] USB 2.0 Camera #2
    
[AVFoundation input device @ 0x7fdf1bd03000] [1] FaceTime HD Camera
    
[AVFoundation input device @ 0x7fdf1bd03000] [2] Capture screen 0
    
[AVFoundation input device @ 0x7fdf1bd03000] [3] Capture screen 1
    
[AVFoundation input device @ 0x7fdf1bd03000] AVFoundation audio devices:
    
[AVFoundation input device @ 0x7fdf1bd03000] [0] Built-in Microphone

    The device[0] is the webcam I want to use.

    Then I tried to capture the webcam using ffmpeg -f avfoundation -i "0" out.mpg

    Output :

    [avfoundation @ 0x7fe7f3810600] Selected framerate (29.970030) is not supported by the device

0: Input/output error

    After that, I tried stream this webcam from my Mac using ffmpeg -f avfoundation -framerate 30 -i "0" -f mpeg1video -b 200k -r 30 -vf scale=1920:1080 http://127.0.0.1:8082/

    Output :

    [avfoundation @ 0x7f8515012800] An error occurred: The activeVideoMinFrameDuration passed is not supported by the device.  Use -activeFormat.videoSupportedFrameRateRanges to discover valid ranges.0: Input/output error

    I cannot capture or stream this webcam. However when I used the Facetime camera instead of this webcam, everything was OK. I’ve been searching for this problem for a few days, but still cannot fix it. Does anyone have experience with webcam and FFmpeg on Mac ?

  • flush encoded packets to disk when muxing audio and video

    23 juin 2016, par chandu

    I am using muxing.c example (without any modifications) provided with ffmpeg 3.0 version to create MP4 file (H.264 & AAC) with VS 2013. The sample is working fine with default width & height for video. But when changed the width to 1920 and height to 1080, sample is taking nearly 400MB (using task manager & in Release mode) through out the program and also never writing the encoded packets to the out file. It is writing to the out file (out.mp4) only when calling avcodec_close() at the end.

    I have tried to

    1. free the encoded packet after calling write_frame().
    2. used avio_flush()
    3. used avcodec_flush_buffers()

    but no success.

    Could anybody please tell me, how can I save the every encoded packet to disk by not keeping in RAM, so the memory usage would be low ?

    Note : There is no issue with flushing the buffers after recording is over, I am doing this by calling av_interleaved_write_frame() with AVPacket NULL.

  • ffmpeg can loop png but not audio

    14 avril 2022, par codingmaster398

    I'm using the following to stream an image to YouTube :

    


    ffmpeg -threads:v 2 -threads:a 8 -filter_threads 2 -thread_queue_size 1080 \
-loop 1 -re -i ./image.png \
-i ./track.mp3 \
-pix_fmt yuv420p -c:v libx264 -qp:v 19 -profile:v high -rc:v cbr_ld_hq -level:v 4.2 -r:v 60 -g:v 120 -bf:v 3 -refs:v 16 -preset fast -f flv rtmp://a.rtmp.youtube.com/live2/xxx


    


    And the looping for the image (to keep it streaming over) works, but not the sound.
