* resample: allocate a large enough output bufferJustin Ruggles2012-03-17
| | | | | Fixes invalid writes and crashes when doing conversions such as stereo to 5.1 channels or sample rate conversion on 5.1 channels.
* wmaenc: remove bit-exact hackJustin Ruggles2012-03-17
| | | | | | It may have improved cross-platform stability, but wasn't the only place in the encoder with bitexact issues. It is no longer needed because we have FATE tests for float encoders using fuzzy comparison.

* threads: fix old frames returned after avcodec_flush_buffers()Uoti Urpala2012-03-16
| | | | | | | | | | Calling avcodec_flush_buffers() and then avcodec_decode_video2() with a 0-sized packet (to get remaining buffered frames) could incorrectly return an old frame from before the avcodec_flush_buffers() call. Add a loop in ff_thread_flush() to zero the got_frame field of each thread to ensure the old frames will not be returned. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* MPV: always mark dummy frames as referenceJanne Grunau2012-03-16
| | | | | | | If the dummy frame are not created from a reference frame they could be deleted untimely resulting in multithreaded decoder waiting on the current frame to finish. Noticed by Ronald S. Bultje in the RV34 decoder with a broken file.
* h264: fix deadlocks on incomplete reference frame decoding.Ronald S. Bultje2012-03-16
| | | | | | | | | | | | | | | | If decoding a second complementary field, and the first was decoded in our thread, mark decoding of that field as complete. If decoding fails, mark the decoded field/frame as complete. Do not allow switching between field modes or field/frame mode between slices within the same field/frame. Ensure that two subsequent fields cover top/bottom (rather than top/frame, bottom/frame or such nonsense situations). Fixes various deadlocks when decoding samples with errors in reference frames.

* h264: stricter reference limit enforcement.Ronald S. Bultje2012-03-14
| | | | | | | | | Progressive images can have only 16 references, error out if there are more, since the data is almost certainly corrupt, and the invalid value will lead to random crashes or invalid writes later on. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* h264: increase reference poc list from 16 to 32.Ronald S. Bultje2012-03-14
| | | | | | | | Interlaced images can have 32 references (16 per field), so limiting the array size to 16 leads to invalid writes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* h264: improve parsing of broken AVC SPSMichael Niedermayer2012-03-13
| | | | | | | | | | | | Parsing the entire NAL as SPS fixes decoding of some AVC bitstreams with broken escaping. Since the size of the NAL unit is known and checked against the buffer end we can parse it entirely without buffer overreads.

* Revert "h264: clear trailing bits in partially parsed NAL units"Janne Grunau2012-03-12
| | | | | | | | | | | | | This reverts commit 729ebb2f185244b0ff06d48edbbbbb02ceb4ed4e. There was an off-by-one error in the bit mask calculation clearing actually the last valid bit and causing http://bugzilla.libav.org/show_bug.cgi?id=227 The broken sample (Mr_MrsSmith-h264_aac.mp4) the commit was fixing does not work after correcting the off-by-one error.
