The function int check_YUV420_input(lav_file_t *lav_fd) in lav_io.c, local variable
double len = 0;
should be declared as
int len = 0;
Also, I am a bit disappointed because it seems lavtrans.c only dump 00dc chunk as JPEG image. In my AVI file created from a Canon digital camera, although the 00dc chunk is in JPEG image format, the dumped JPEG image can not be viewed by any JPEG viewer. I check the 00dc chunk and it seems to be the first Quantization Table (DQT) uses precision 0 and read 64 bytes data, the 2nd table uses precision 1 and read 128 bytes data, but the total size of DQT section is only 132, so the JPEG decoder don't think this is a valid JPEG file. Anyone can help me with this problem?
Thanks.
Bo
