* avcodec/hcadec: get intensity from correct channelsummertriangle.dev@gmail.com2020-06-21
| | | | | | | Fixes an issue with one output channel being slightly louder than the other. The output now matches other public HCA decoders. Signed-off-by: t <summertriangle.dev@gmail.com>
* avcodec/hcadec: fix decoding of hfr channelssummertriangle.dev@gmail.com2020-06-21
| | | | | | | | I suspect this was originally broken by b7e5c8f , but even then, it only worked because it read out of bounds from intensity_ratio_table. Signed-off-by: t <summertriangle.dev@gmail.com>

| | | | Commands are unsigned so be consistent.
* avcodec/ccaption_dec: do not modify packet data in case of parity errorPaul B Mahol2020-06-20
| | | | To dissallow similar errors in future, make pointers const.

* avcodec/encode: restructure the core encoding codeJames Almer2020-06-18
| | | | | | | | | | | | | | | | This commit follows the same logic as 061a0c14bb, but for the encode API: The new public encoding API will no longer be a wrapper around the old deprecated one, and the internal API used by the encoders now consists of a single receive_packet() callback that pulls frames as required. amf encoders adapted by James Almer librav1e encoder adapted by James Almer nvidia encoders adapted by James Almer MediaFoundation encoders adapted by James Almer vaapi encoders adapted by Linjie Fu v4l2_m2m encoders adapted by Andriy Gelman Signed-off-by: James Almer <jamrial@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.
