video-streaming

问题 I have implemented Android and MJPEG and also implemented async and certifications to run it that is mentioned here. Now i have managed to run the jpeg video stream but the issue is It keeps blinking when running the stream. It keeps getting on and off. I think it could be the issue of frames.

问题 I want to capture a video from a real webcam, apply filters with openCv and write the filtered video on a virtual webcam, to stream it on web.

Thanks 回答1: Well, actually this is possible. A quick and dirty way to do this is to use WebcamStudio. That will create a new video device (e.g., /device/video2) that other programs see as

问题 I'm looking for some universal way to dump rtsp stream. I want to figure out, that some rtsp stream is working well and server is sending some watchable video. openRTSP At first, google recommends me openRTSP tool. openRTSP -4 ${stream_link} > ${output_file} But output video file dumped by that tool is not really correct. Video decoder (ffdec) returns many errors like "Failed to decode video packet" and "[h264] no frame!", which don't suit me. ffmpeg Then I've tried to dump rtsp stream with
