• Audio format not supported in Flash Media Live Encoder from Directshow Audio Filter

  1er novembre 2015, par Hamed GH

  I create a virtual audio filter in DirectShow and introduce it as a AudioInputDevice.

  When I select this filter as a Directshow Device in FFMPEG, it’s working without any problem. But in Flash Media Live Encoder(FMLE) it’s not working.

  FMLE said "Audio format not supported" when selecting my filter as the Audio Device.

  I searched in internet and found the following link. But implementing GetStreamCaps not working for me.

  Would you please tell me what is the problem ? or which audio connections FMLE accept ?

• mpegts proxy allowing multiple concurrent views of same source feed

  5 juillet 2018, par Yass T

  I am having trouble finding a (preferably non-commercial) linux compatible project that would allow to "restream" one particular MPEGTS live source feed to multiple clients, without requesting it more than once from the source.

  Imagine an mpegts live source feed coming from http://my_mpegts_provider (imagine we have the direct link, no m3u style playlist), I would like a program to be able to grab that source and proxy it to one AND more client devices (let’s say VLC players) when they are requesting it, even if not requested at the same time.

  In other words, can we proxy the MPEGTS stream so only our proxy will be seen as the "client" (from the source provider point of view) when multiple devices (on the same network) connect to the SAME source on this side ?

  I tried the node-ffmpeg-mpegts-proxy but it clearly showed two separate connections to the source when asking for the same "channel" with two different VLC clients (confirmed with netstat).

  Thanks, and sorry in advance if my post is out of stackoverflow rules, I can’t think of a better place to gather some good opinions

• Need to hide error logs used on video capture with Open CV and Python

  16 août 2024, par Rodrigo Aliaga

  Title : How to hide OpenCV RTSP connection errors in Python ?

  


  I am using OpenCV (4.8.0) with Python to test some RTSP connections. When I run the code, I see these logs on the console :

  


  [rtsp @ 0000029b73b233c0] method SETUP failed: 500 Internal Server Error
[rtsp @ 0000029b73b233c0] method SETUP failed: 500 Internal Server Error
[rtsp @ 0000029b73b218c0] method SETUP failed: 500 Internal Server Error
...
...


  


  I want to hide these errors (or any other warnings) from OpenCV. Below is the function I am using :

  


  cap = cv2.VideoCapture(url)
if not cap.isOpened():
    # print(f"Failed to open RTSP stream: {url}")
    result = False


  


  I know that in OpenCV with C++, there is an option to set cv::utils::logging::LogLevel LOG_LEVEL_SILENT = 0. Is there something similar available in Python ? Or is there another way to suppress these warnings and errors ?

  


  Thanks in advance !
