Dear Ross,<br><br>I have developed a RTSP streaming server that supports H264 and M4V-ES and I am now trying to implement Trick Play functionalities.<br><br>In order to support fast forward and reverse play, I have understood that I need to work with "scale". <br>
For a scale = 2.0, I have understood that I need to send only 1 frame every second frames.<br><br>--> While streaming an H264 file with scale=2.0, I have tried to stream key frames (IDR Nalu) and discard every second frame (SLICE Nalu) : this doesn't work at all since every SLICE seems to need the previous SLICE along with the key frame to be decoded. <br>
<br>Thus my question : while fast forwarding an H264 file should I only stream key frames ? <br><br><br>Thanks in advance for your response!<br>guillaume<br><br><br><br>
