Thanks for your mpeg program!
I've done this:
if (bytes_read <= 0) {
if (bytes_read < 0) {
vbiprintf(stderr, L"Cannot read %s (%d:%s)\n", input,
errno, strerror(errno)); if (opt.printverbose >= 1) {
vbiprintf(stderr, L"%s terminated.\n", PROGRAM);
}
return 2;
}
(changed return 1 to return 2)
then, at the end:
if (finished == 2) {
exit(1);
}
return 0;
}
I added an exit(1). This way, I get a return code of 1 when the device is
inaccessible, and can avoid taking action when the device is busy.
Thanks again! This should help with my debugging!
