Place regression test output files in subdirs per family
Originally committed as revision 22155 to svn://svn.ffmpeg.org/ffmpeg/trunk
Correct opts calulation in ffmpeg.c.This correct the stop point for demuxing with -vcodec copy and -t as well aspacket interleaving. (we already diddrop packets but kept demuxing themfor too long due to opts being wrong)the change to ffm is due to 2 packets with timestamp 0 being stored...
regtest: split reference files allowing tests to run individually
With this change, the output is checked immediately after each testhas run. This means commands like "make regtest-mpeg2" can now beused to run a single test and get meaningful results....
