Hi DarkSylinc,
i have done already the encoding part using the xvid_encraw as reference forthe encoding of the video, no problem with the playback of the encoded videoand right now i am stock with the decoding part of the compressed video that ihave. specifically in the reading of the compressed video file from directoryjust like what the xvid_decraw did in the decompression of the compressed videobut the only problem is when i read the file i get zero as a return value inreturn decompression does not decompress any data at all: this is exactlywhat i did in the reading of the .m4v file
1. open the file through
FILE *fpi = NULL;
fpi = fopen("c:\\sample_file.m4v","r+b");
if(fpi==NULL)
Msg(TEXT("Error openingthe file"));
I GOT NO ERROR WHEN OPENING THE FILE...
2. determine the buffer size to allocate for the read stream buffer through
fseek(fpi,0,SEEK_END);
long lFileSize = ftell(fpi);
unsigned char *buffer = NULL;
buffer = (unsigned char *) malloc (lFileSize);
int useful_bytes = fread(buffer, 1, lFileSize, fpi);
if(useful_bytes==NULL)
Msg(TEXT("Errorreading to file"));
I GOT ZERO BUFFER VALUE HERE!..
looking forward to hear from you....
thank you for the time...
regards,
reno
