Re: [Live-devel] Open H.264 stream frame by frame

2014-09-25 Thread Ross Finlayson
As others have noted, the "LIVE555 Streaming Media" code doesn't include any 'codec' (i.e., audio/video decoding or encoding) functionality. If you want to actually decode an incoming RTSP/RTP stream, you'll need to use separate decoding software. If you want to process the H.264 NAL units for

Last year when I did this, decoding h264 with libavcodec required finding specific nals, the sps and pps, and holding on to them for all subsequent decode calls. What you'll likely end up needing to do is to figure out at what point in the live555 library the encoded data is available to be re

Hi Marcin, You'll have to use libavcodec to get decoded frames ( frame / frame) and then convert the received frame to either Iplimage or Mat whichever you prefer. You can check sample code given under ffmpeg sources to see how you can use libavcodec. On Sep 24, 2014 4:38 PM, "Christiano Belli"

Hi, Really - i think that you have to decode the stream to get frame-by-frame data for further analysis. Soon Ross will reply also that Live555 is not responsible for decoding/encoding stream but only for reciving it. I think you have to use ffmpeg or libavcodec for example to decode bitstream

Hello, I'm new with live555 and I'm so exciting in learning this. I have some questions: There is a way where I can get the RTSP/H.264 stream from a ip camera and get each frame from video to do video analytics with openCV per example. Does the process to get each frame from a RTSP/H.264 stream n
