Hi<br>I need to using H264 to live broadcast and it need 25 frames in one second., so I need to encode 25 frames <br>in one second. If the frame is 160*120 or 320*240 ,it is ok. But if it is 640*480, it need more than 70ms to <br>
encode one frame. Does anyone have suggestion about how to increase encode and decode speed?<br><br>Thanks Hongzhen Nan<br><br></blockquote></div><div><br>If you don't have h/w support for h264, I would consider MPEG4 encoder, which is much faster both for encoding and decoding (but looses on compression).<br>
