  • vulkan : do not create imageviews with video encode/decode usage

    vulkan : do not create imageviews with video encode/decode usage

    This function is only used for filtering and generic compute.
    
The issue is that a view inherits the usage flags from the image
    
by default, and the spec says the view format must be compatible
    
with the usage. VkImageViewUsageCreateInfo allows us to filter out
    
the indeded uses of the imageview.
    

    Pffff.

  • Receive RTSP stream within docker container

    12 août 2021, par Wayne

    I am trying to decode a camera rtsp stream using ffmpeg_libs within a ubuntu docker container. The ffmpeg debug output seems to show that it successfully negotiates the rtsp-digest authentication (ie. RTSP/1.0 200 OK), and receives an SPS (nalu 7) and PPS (nalu 8), but nothing after that. It times out, retries, etc. That doesn’t really make sense to me.

    



    The same code compiled and run locally (not in docker) works fully.

    



    Also, if I decode a file, the code works fine both locally and in docker container. So, the basic ffmpeg_lib decode is working. The difficulty is with the stream interface running in docker.

    



    Is there additional authentication through the docker interface, or maybe port access, or something ? I’m not much of a networking guy, so I’m really lost at this point.

    



    The ffmpeg logs is below, and my docker run command is :

    



    docker run -it --name VideoRx videorx:latest (also tried with -p 554)


    



    Any help will be very much appreciated.
    
Thanks,
Wayne

  • high CPU usage with ffmpeg and youtube live stream

    21 mai 2018, par Sergio santa

    I have a problem with high CPU usage using FFmpeg to stream my videos via youtube.
    my main purpose is to stream loop videos as long as possible but after 6 hours the stream stops and the CPU usage was almost 90%.

    the code I’m using

    ffmpeg -re -stream_loop -1 -i video.mp4 -vcodec libx264 -preset veryfast -maxrate 2500k -bufsize 3368k -vf "format=yuv420p" -g 60 -acodec libmp3lame -b:a 198k -ar 44100 -f flv -s 1280x720 -max_muxing_queue_size 400 rtmp://a.rtmp.youtube.com/live2/xxxxxxxxx

    My VPS details :
    1 vCPU, 3 GB memory
