Reimar Döffinger 3214db98ea Improve dxa probe by checking the values for width and height are reasonable. 
Originally committed as revision 19897 to svn://svn.ffmpeg.org/ffmpeg/trunk
 2009-09-17 18:08:07 +00:00
Reimar Döffinger 892d7e78ef Slightly improve probe for ea format by checking that it is possible to 
guess whether the file is little- or big-endian.

Reimar Döffinger a5083f66c7 Add dnxhd test to regression tests.

 2009-09-17 18:06:03 +00:00
Reimar Döffinger 0d6da4b831 Fix overflow check insufficiently improved in r19840. 
It assumes that sizeof(vmd_frame) < 64k, otherwise an additional
check to ensure sound_buffers <= UINT_MAX / sizeof(vmd_frame) would be necessary.

Reimar Döffinger 3489e150d9 Slightly stricter MPEG-PES probing, fixes issue 1383. 
Originally committed as revision 19852 to svn://svn.ffmpeg.org/ffmpeg/trunk
 2009-09-15 10:01:25 +00:00
Reimar Döffinger 5837e4ca33 Vastly improved mm_probe function, passes probetest. 
Originally committed as revision 19851 to svn://svn.ffmpeg.org/ffmpeg/trunk
 2009-09-15 09:21:29 +00:00
Reimar Döffinger 97e078087b Improve sierravmd probe. It is still quite weak, but further improvements 
are non-obvious and probably need a large (about 1kB at least) probe buffer.

Originally committed as revision 19850 to svn://svn.ffmpeg.org/ffmpeg/trunk
 2009-09-15 09:16:29 +00:00
Reimar Döffinger 6377de611a Try harder to avoid false positives for DV probe. 
Require at least one signature match per provided 1MB of probe data,
and if there is only a single match, return at most MAX/4.
Fixes issue1382 but could/should probably still be improved.

Originally committed as revision 19848 to svn://svn.ffmpeg.org/ffmpeg/trunk
 2009-09-14 22:03:07 +00:00
Reimar Döffinger 98487a5b69 Make dnxhd probe more strict, fail if we detect values in header that would 
make our decoder fail anyway.
dnxhd probe now passes probetest.

 2009-09-14 21:50:23 +00:00
Reimar Döffinger 05bdd33a12 Make DTS probe more robust against false positives (as e.g. probetest shows). 
In particular check that the detected markers clearly indicate a specific DTS
format (a wild mixture of e.g. little- and big-endian markers is unlikely to be
a valid DTS file) and ensure the markers appear with sufficient frequency.

 2009-09-14 20:28:10 +00:00
Reimar Döffinger 9f449d57c7 Check the index validity more thoroughly for the c93 probe function. 
In particular, check that length of the first index entries is not 0 since
that is interpreted "end of file" and makes no sense in the very first entries.

Originally committed as revision 19843 to svn://svn.ffmpeg.org/ffmpeg/trunk
 2009-09-14 20:01:32 +00:00
Reimar Döffinger ddbb7c9be2 Add more sanity checks for header elements, rejecting files with clearly 
invalid values that wouldn't play right anyway and reduce probe score to MAX/2.
Passes probetest v2.

 2009-09-14 19:58:51 +00:00
Reimar Döffinger 21ab5c5827 Extend check for integer overflow for malloc argument to take into account 
also the addition of "sound_buffers" not only the multiplication.

Originally committed as revision 19840 to svn://svn.ffmpeg.org/ffmpeg/trunk
 2009-09-14 17:15:18 +00:00
Reimar Döffinger 8466ab59b2 Check buffer size for idcin check, otherwise false positives are too likely for 
small probe buffer sizes due to 0-padding (see probetest results).

 2009-09-14 15:44:05 +00:00
Reimar Döffinger cbb5da57cd When resetting vst->pkt.data to NULL, also set vst->slices. 
This avoids a crash when the next slice is not a start slice and thus
pkt->data is still NULL.
This probably only happens with broken or unsupported files like
http://samples.mplayerhq.hu/real/multirate/JustaSpa1937_64kb.rm
that need further fixes, but keeping vst state consistent is still a good idea.

Reimar Döffinger 19a9a49e84 Simplify: reget_buffer behaves exactly like get_buffer if the buffer was 
previously released, so no extra condition is necessary.

Reimar Döffinger 46f3b40eb3 Add warnings to av_strlcat and av_strlcpy doxygen that the input strings 
already must be properly 0-terminated strings. Unlike strncpy it
cannot be used on raw data read from a file.

Reimar Döffinger a2f3851166 mov_read_packet: if dv_get_packet fails, return exactly its error value 
instead of always -1 (makes no real difference currently since dv_get_packet
always returns -1 so far).

Reimar Döffinger 69fc436cbc In mov_read_packet remember the AVStream we want to demux next instead of the 
MOVStreamContext. We need the AVStream anyway and it is easier to get the
MOVStreamContext from the AVStream than the other way around.

Reimar Döffinger 10f9ff9bf6 Set AV_PKT_FLAG_KEY in avcodec_decode_video. 
This fixes decoding of MPNG, which currently is incorrectly decoded as
CorePNG delta frames.
CorePNG can not be correctly decoded via this old API either way.
