  • FFMPEG on ubuntu wont start. Process is just killed [on hold]

    8 novembre 2018, par AK47

    I am trying to run a command on ffmpeg. When I run on my local computer it works fine but when running on my ubuntu server it won’t start. It just keeps giving an error saying the process is killed when it trys to start. Is this something related to memory or a different issue ?

    Any help would be greatly appreciated

  • ffplay 461 Unsupported transport

    28 octobre 2017, par Cerato

    Please help me to understand what I am doing wrong.

    I am executing the following command for making a live stream

    Executing: powershell gst-launch-1.0 filesrc location=D:/testVODs/sample.mkv ! matroskademux name=dmx dmx. ! h264parse config-interval=1 ! queue ! rtspclientsink profiles=avpf protocols=udp location="rtsp://192.168.1.1:8554/8c83bea4-b49b-4776-9c0f-d11e9e8898f0/1" name=rtsp_out dmx. ! opusparse ! queue ! rtsp_out.

    and in the result, I see that the execution ended after 00:01:21 which means that the stream is ended successfully after my video ended :

rtsp://192.168.1.1:8554/live/8c83bea4-b49b-4776-9c0f-d11e9e8898f0/1: Unknown error

    why method SETUP failed as 461 Unsupported transport and how it can be solved ?

    I tried to use different ffplay, ffmpeg commands, but all of them lead to the same result.
    If I do not use rtsp_trasport command I have the error [udp @ 000001d1ab52c300] ’circular_buffer_size’ option was set but it is not supported on this build (pthread support is required)
    and the same 461 Unsupported transport

    Before I added "profiles=avpf" to my stream creation request I managed to play it successfully with "rtsp_transport tcp".
    But now profiles=avpf is required and I need to understand how to deal with it

  • FFmpeg library (ver 5.1) multithread decode and scaler

    19 août 2022, par wolverin

    I wrote my own code that takes the video from v4l2 MJPEG and streams it to the rtsp server in H264.

    


    Everything is fine as long as the incoming and outgoing stream resolution is 640x480, but if the incoming is 1920x1080 and I do sws_scale, then decoding and scaling are very slow.

    


    If I run ffmpeg from the command line, I see swscale errors, which means that sws_getContext is called 20 times, which means a queue of 20 scaling threads is created
