I have narrowed the problem down to a loop in the
int mov_check_file(demuxer_t* demuxer)
routine. The last message that is seen from 'mplayer -v -vcd 2' is:
VCD start byte position: 0x1546E0 end: 0x670C76C
Checking for YUV4MPEG2
ASF_check: not ASF guid!
Checking for NuppelVideo
Checking for MOV
is "Checking for MOV". Using gdb I've seen that no return is
ever made from 'mov_check_file' if a VCD/SVCD is in the drive.
There is a comment in libmpdemux/demux_mov.c that was not present
a while ago:
else if (len == 0) /* deleted chunk */
/* XXX: CJB! is this right? - alex */
else if(len<8) break; // invalid chunk
Could this be leading to an endless loop somehow?
