DM355 MPEG4 720p cmem error

2008-07-25 Thread Kumar Bala
Hi, I have HD camera connected to DM355 through the J30/J31 connector. I have configured the vpfe driver to read from this device. Everything works great in NTSC/PAL or VGA. I have a BT601(16 bit) interface. My application layer reads the frame from the vpfe(using Q/DQBUF ioctl) and converts it in

Helly Anthony, And what data size do you use ? The outBufDesc.bufs[0] contains the MPEG4 frame and outArgs.bytesGenerated contains the size of the frame. Ideally your fwrite should be somethinf like this fwrite((char *)outBufDesc.bufs[0],1,outArgs.bytesGenerated,fp); [EMAIL PROTECTE

Hi, I have an MPEG4 streaming system which capture live video at 1280x720p using a HD camera module. Then it streams it over to a PC running the client app such as VLC or mplayer. I believe I get a few hundred millisecond latency (about 200-300 ms). We want to achieve a near analogue latency. I a

Improving Ethernet performance on dm355

Hi, We are trying to improve the ethernet performance on the DM355 EVM. The current performance index as per the TI driver guide is about 26 MBits/s. I was wondering if the current driver uses DMA ? If uses DMA , what are the other areas to work on to improve performance. We would ideally like to

Hello, If you want to play the file locally using VLC, then rename the file to .*m4v* But if you want to stream it and play it over rtsp then you need to modify your rtsp streamer (from live555 example) in order to parse the short header generated by DM355. More information on this can
