* avcodec: Add const to decoder packet data pointersAndreas Rheinhardt2022-07-09
| | | | | | | The packets given to decoder need not be writable, so it is best to access them via const uint8_t*. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/aacdec: fix parsing of dual mono filesJames Almer2022-07-08
| | | | | | | | | | Dual mono files report a channel count of 2 with each individual channel in its own SCE, instead of both in a single CPE as is the case with standard stereo. This commit handles this non default channel configuration scenario. Fixes ticket #1614 Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/openh264: return (DE|EN)CODER_NOT_FOUND if version check failsAndreas Schneider2022-07-08

* avcodec/libx265: make X265 CSP selection pixel format independentJan Ekström2022-06-27
| | | | | | | | Currently the format listing misses the J formats completely, yet they are marked as supported in the encoder. Thus to make the logic support them while not explicitly listing them, make the logic utilize chroma subsampling information in both width and height available through the pixel format descriptor.

| | | | | | | | | | Forgotten in 4011a76494a5ff6844312813bc753aae8e54c2f0. The reason for this is that these functtions are marked as av_always_inline and GCC does not emit warnings if such functions are unused, so this went unnoticed.

* avcodec/hevc_sei: Fix check for SEI endAndreas Rheinhardt2022-06-24
| | | | | | | | | | | | | | The intention behind the current check seems to be to check for the rbsp_trailing_bits() syntax structure which is always 0x80 for valid SEI messages. Yet this is wrong: These trailing bits are not part of the GetBitContext -- they have already been stripped in ff_h2645_packet_split(). And it is harmful, as 0x80 is a legal SEI message payload type (namely for Structure of pictures information SEI messages). We ignore this type of SEI, but because of this bug we also ignored every SEI message in the same NALU following it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
