dear all
I am using 6437,I have a puzzle about h264 decode,now i can encode my video and send it to computer by JTAG, and I can play this encoded video by TCPMP,but now ,I want to transfer my encoded video to another equipment through mcbsp,as jtag is too slow. so I need to decode the video by dsp,but from the examples of C:\dvsdk_1_01_00_15\examples\video_encdec ,decode needs parameters of encode,as
status = VIDENC_process(enc, &inBufDesc, &encodedBufDesc, &encInArgs, &encOutArgs);
Memory_cacheWbInv(encoded, encOutArgs.bytesGenerated);
if (status != VIDENC_EOK) {
printf("Encoder frame %d processing FAILED, status = 0x%x, "
"extendedError = 0x%x\n", n, status, encOutArgs.extendedError);
break;
}
fwrite(encoded,encOutArgs.bytesGenerated,1,fh_enc);
/* Reuse the video input frame for display exchange: */
dst = frameBuffPtr->frame.frameBufferPtr;
if (encOutArgs.bytesGenerated == 0)
{
printf("Frame %d dropped\n", n);
}
/* decode the frame */
decInArgs.numBytes = encOutArgs.bytesGenerated;
status = VIDDEC_process(dec, &encodedBufDesc, &outBufDesc, &decInArgs,
&decOutArgs);
now if I depart this project into two,ons is encode,the other is decode,how can I get the parameters generated by encode? thanks.
ps: from spruev6,Page 29,there is a setence: Note that the input video and audio files need to be "raw" files. These do not contain header information, just raw H.264, MPEG4, and G.711 data. You can download the free VLC Media Player utility,
which can convert standard media files to "raw" files.
Do I need to download vlc?
