  • use OpenCV to capture a good frame of faces from IP camera [on hold]

    17 octobre 2018, par wiwengweng

    everyone. I am working on some research about getting frames from IP camera, and then detect and recognize faces. There is some implements on the last two steps. And my first problem is to judge if a frame with faces is good enough for detection. Video stream is read by OpenCV and/or ffmpeg, and there are many ways to capture frames one by one.

    As we know, people are always walking through, so frames captured from IP camera is not always good. But the good news is the if we extract the frames from the IP camera video file, we find some frames good enough for detection.

    is it possible to analyse by using the opencv CascadeClassifier to detect if the face is clear or not ? Right now I just use minSize and maxSize to capture the face, however I cannot judge if it is clear.

    I also try de-blurring pictures of frames using GAN, but that will need more time, so I think that is not an ideal way. So any advice is welcome.

  • How do I live transcode a wmv file for playback in html5 player ?

    14 octobre 2018, par steven

    I’ve been working at this for quite awhile and still haven’t found a solution that works. I need a way to live convert (transcode) a .wmv file for playback in a html5 web player.

    I have a linux server (Apache) setup to stream video files through an html5 web player (Video.js) designed for Chrome and Firefox browsers. The file types I am dealing with are .mp4 (H.264), .mkv, and .wmv. The good news for me is that I can deal with mp4 and mkv natively, however I can’t play wmv. Also, I have to deal with a lot of files, change periodically, and can be quite large.

    After doing a lot of research and reading many times how you can’t stream wmv directly, I came to the realization that I had two options. Either convert the file to a supported format or live transcode a file for use in the web player. Due to the amount of files and their size (and periodically changing) converting the file is simply not feasible. So I am stuck with live streaming/transcoding. I figured ffmpeg would be the way to go, but I have yet to figure out how to get ffmpeg to live stream into the html5 player.

    So how do I take an existing .wmv file and live stream it in an html5 player ?

    The things I’ve tried so far :

    Tried creating a m3u8 playlist and hoping it would magically work.

    ffmpeg -i "hello.wmv" -s 640x480 -c:v libx264 -f ssegment -hls_flags delete_segments -segment_list playlist.m3u8 -segment_list_type hls -segment_list_size 10 -segment_list_flags +live -segment_time 10 out_%6d.ts

    Simply copying to mp4 and streaming while ffmpeg still progressing. Obviously didn’t work.

    ffmpeg -i "hello.wmv"  -vcodec copy video.mp4

    Converting to webm format and streaming webm while ffmpeg still progressing. This actually did show the video for a few seconds in the html player :

    ffmpeg -i "hello.wmv" -codec:a libvorbis -codec:v libvpx -b:a 128k -b:v 1200k video.webm

    Ffmpeg is not required to be used (was thinking of vlc as well), the html5 player is required. Completely converting then streaming isn’t a viable option because file sizes can be too large and change periodically. What command/program can I use to stream the file for playback in the html player ?
