I have search for source example on how to decode an MPEG4 streaming from a hardware video capture device. All I found is example from a file, witch does not help me a lot.
Here is a little description of my setup: * Using Ubuntu 8.10 * A USB video capture device from Sensoray (2251) (http://www.sensoray.com/products/2251data.htm) * An embedded PC from Versalogix (http://versalogic.com/products/ds.asp?productid=200) Here is a little description on the data path: * NTSC analog camera plug into the USB capture device * Capture device hardware encode in MPEG4 (MPEG4 is a must to minimise HD capacity and data transfer) * Encoded frame buffers are sent to the PC via USB. * Frame buffer are appended into an .mpg file. * No display is needed. * Once done data is transfer to external path. Even if no display is needed, some image processing need to be done in REAL TIME. Since I have access to the buffer itself, it's size and also it's type (I-frame, B-frame, P-frame), I could use ffmpeg to decode frames. So if somebody can help me to get started with that, I would really appreciate. If B and P frame are too complicated to decode, only decoding the I-Frame would be enough for my application. Only decoding I-frame will also minimise the latency of my low power CPU, so that's a good thing.
