* libavcodec/jpeg2000dec.c Fixed WRITE_FRAME and tile co-ordinates:Gautam Ramakrishnan2020-06-27
| | | | | | | | | | libopenjpeg2000 uses ceiling division while dividing tile co-ordinates with the sample separation. Also, corrections were made to the WRITE_FRAME macro. Improves: p1_01.j2k and p1_07.j2k Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* lavc/aac_ac3_parser: improve the raw AAC file bit rate calculationJun Zhao2020-06-26
| | | | | | | | | | | | | | | | | | | Now we just use one ADTS raw frame to calculate the bit rate, it's lead to a larger error when get the duration from bit rate, the improvement cumulate Nth ADTS frames to get the average bit rate. e,g used the command get the duration like: ffprobe -show_entries format=duration -i fate-suite/aac/foo.aac before this improvement dump the duration=2.173935 after this improvement dump the duration=1.979267 in fact, the real duration can be get by command like: ffmpeg -i fate-suite/aac/foo.aac -f null /dev/null with time=00:00:01.97 Also update the fate-adtstoasc_ticket3715.

* avcodec/nellymoserdec: Don't use invalid AVPacketSideDataTypeAndreas Rheinhardt2020-06-22
| | | | | | | | | | | | | | | | | | | Commits 957a593cd95b15a5dcb2f50306fbac59f09d8e9e and 11828b8885cc1d87ffc7b1b4bbe642ce9720b194 made the flv demuxer export a certain flag as side data to be used by the nellymoser decoder for mid-stream sample rate changes. It used a custom side data type 'F' that was never officially documented. Yet since 2215c39e94e01f57b3191a29e0e51d7e230daf49 (merged in commit 52c522c72090233edeeb0486a9bd8bee925a710a) this information is exported via the properly documented AV_PKT_DATA_PARAM_CHANGE side data. The merge commit therefore stopped exporting the 'F' sidedata; yet the changes in the Nellymoser decoder (which are now dead code (and would become dangerous if lots of new side data types were added)) have not been removed. This commit does this. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avcodec/iirfilter: Fix memleakAndreas Rheinhardt2020-06-15
| | | | | | | | | | | | | | | Commit 17e88bf0df21906633a7d36d9f2aeeeb5b6d3267 created a memleak by removing a call to ff_iir_filter_free_coeffsp on error; this has been found by Coverity (ID 1464159). This commit fixes the memleak by readding the call to ff_iir_filter_free_coeffsp. Notice that this is not a simple revert, because several macros that were used before 17e88bf0df21906633a7d36d9f2aeeeb5b6d3267 were replaced in commit 44863b2c2d5a31d82aafa71cdbd180d6bfbed5b4 and completely removed in 2658680df4fc606522e5f65899afb9a98b47d287.

* avcodec/hevc_mp4toannexb_bsf: Check NAL size against available inputAndreas Rheinhardt2020-06-15
| | | | | | | | | | | | | | | The hevc_mp4toannexb bsf does not explicitly check whether a NAL unit is so big that it extends beyond the end of the input packet; it does so only implicitly by using the checked version of the bytestream2 API. But this has downsides compared to real checks: It can lead to huge allocations (up to 2GiB) even when the input packet is just a few bytes. And furthermore it leads to uninitialized data being output. So add a check to error out early if it happens. Also check directly whether there is enough data for the length field.
