Kostya Shishkov 8355572f91 lavc MJPEG decoder is capable of decoding some extended sequential
Huffman-compressed JPEG files, so make it decode those files
(samples are welcome).
This fixes issue 1420

Reimar Döffinger 82c9182fe3 If the end of the input buffer is reached while decoding MJPEG and at least
a valid SOF was found, emulate an EOI.
This allows e.g. to at least decode the available part of incomplete MJPEG frames.

Reimar Döffinger 1496b04c28 Make the MJPEG decoder return -1 when no image was decoded so that decode
errors are actually recognizable as such.

Reimar Döffinger 643fd8a198 Add a got_picture flag to MJpegDecodeContext which indicates if its picture
element is valid. Skip the code handling SOS and EOI if not, since it can not
work without a valid AVPicture.
This fixes a crash with mjpeg/smclockmjpeg.avi.1.0 from issue 1240 where the
decoder returned an invalid AVPicture.

Reimar Döffinger b27bf2a7b4 mjpegdec: check that the coded dc_index and ac_index have a valid associated VLC table.
Removes some disabled dc_index/ac_index checking code that seems to have had
some undocumented issues and should not really be necessary anymore now.
Fixes from issue 1240 the files mjpeg/smclockmjpeg.avi.1.10 and mjpeg/smclockmjpeg.avi.1.171.

Thilo Borgmann 7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread
"Google Summer of Code participation" on the mailinglist.

Vladimir Voroshilov 3c3704d281 Fix MJPEG decoder for AMV files.
Since decoding is doing from the end and aligned by 16
previous code worked correctly only when picture height was dividable by 16,
otherwise it provides garbage in top lines and truncates bottom.
New code adjusts data[] pointers taking in account alignment issue.
