Errors when use mps in NVDEC ?
4 avril 2019, par johnsondengI use
ffmpeg
compiled withcuda
, supportnvdec
to decodeh264
in gpu devices. MPS(https://docs.nvidia.com/deploy/mps/index.html) can share context with different processes, and this can use less gpu storage when use multi-process to decodeh264
stream. But when I useffmpeg
in this mode, error got like this.Input #0, mpeg, from '/data/yt_traffic/media/nianjianbiao.mp4':

Cannot get MediaStream from Electron app to browser via Openvidu media server
11 juin 2021, par foxy.bunnyI'm currently having an issue with openvidu-browser-2.17.0.js


I'm trying to transfer a camera stream from RTSP to an Openvidu media server deployed on cloud and get the stream back on the browser.


The RTSP stream was converted into an HLS stream using FFmpeg and played using hls.js. It was captured in an video tag in HTML and I used the HTMLMediaElement.captureStream().getVideoTrack() to generate MediaStreamTrack and passed it into the videoSource property in initPublisher. This publisher part was wrapped in electron. Then, the stream was connected to our cloud Openvidu server deployed on-premises exactly like in the Docs (https://docs.openvidu.io/en/2.18.0/deployment/deploying-on-premises/). The subscriber part is a simple HTML page displayed on the browser to get the stream from the cloud server. The subscriber is responsible for creating session and generating stream from the media server when streamCreated event occurs.


The whole workflow worked nicely when we tested it with our webcam, however, when we use MediaStreamTrack of our stream video instead of webcam, the subscriber part only showed the blank video.


My question is :


1 : Is it possible to stream an MediaStream to Openvidu media server like that ?


2 : If yes, then what am I doing wrong here ?


Describe the bug


Cannot get MediaStream from Electron app to browser via Openvidu media server.


Expected behavior


Receive the stream from the Electron app to browser via Openvidu media server.


Wrong current behavior


Only get blank video
