Re: [Live-devel] Scaling a H264 elementary stream

I implement fast forward, and reverse play, and stepping forward and backward, but I do it from a buffer on the client. I thought Reverse required a buffer. Can rtsp stream backwards, By gop obviously, since diffframes depend on keyframe This message and any attachments contain confidential a

[Live-devel] RTP stream retransmit

2013-01-30 Thread Zvika Meiseles
I've written some code using the live555 library that receives an RTP MPEG2 stream, converts it to TS and transmits it using RTP to another address. The incoming RTP stream is a live feed coming from a camera. In order not to be vulnerable to networking delays, I've implemented a FramedFilter that

Yes, this seems like a good way to implement fast-forward and slow-motion, provided that (1) the network and receiver can handle the increased bitrate when you increase the scale factor - as you noted, and (2) the receiver can properly handle frames that arrive at an 'unusual' frame rate. By th

[Live-devel] Scaling a H264 elementary stream

2013-01-30 Thread Bruno Abreu
Hello everyone, we've just developed a H264 video stream filter that allows scaling. Fast-forward and slow-motion, only, reverse-play is not contemplated. It works by adjusting the presentation time and frame duration of each frame based on the current scale factor, thus speeding up or slowing do
