* avcodec: add constants for KLV pseudo-profile.Brad Hards2020-05-311-0/+3
| | | | | | | | | | | | | | | | | There are two different ways KLV is used in MISB specs - sync and async. The corresponding text (in ST1401) says: ISO/IEC 13818-1 Table-34 defines a stream_type = 0x15 for “Metadata carried in PES packets,” and Table 2-22 defines a stream_id = 0xFC for “metadata stream.” and In ISO/IEC 13818-1, Table-34 defines a stream_type = 0x06 for “PES packets containing private data,” and Table 2-22 defines a stream_id = 0xBD for “private_stream_1.” These constants allow us to distinguish the two cases, as codec profiles.

* lavc/hevc_refs: Fix the logic of find_ref_idx()Xu Guangxin2020-05-271-18/+20
| | | | | | | | | | | | | | | | | | | | | | | | | Currently find_ref_idx() would trigger 2 scans in DPB to find the requested POC: 1. Firstly, ignore MSB of ref->poc and search for the requested POC; 2. Secondly, compare the entire ref->poc with requested POC; For long term reference, we are able to only check LSB if MSB is not presented(e.g. delta_poc_msb_present_flag == 0). However, for short term reference, we should never ignore poc's MSB and it should be kind of bit-exact. (Details in 8.3.2) Otherwise this leads to decoding failures like: [hevc @ 0x5638f4328600] Error constructing the frame RPS. [hevc @ 0x5638f4328600] Error parsing NAL unit #2. [hevc @ 0x5638f4338a80] Could not find ref with POC 21 Error while decoding stream #0:0: Invalid data found when processing input Search the requested POC based on whether MSB is used, and avoid the 2-times scan for DPB buffer. This benefits both native HEVC decoder and integrated HW decoders. Signed-off-by: Xu Guangxin <guangxin.xu@intel.com> Signed-off-by: Linjie Fu <linjie.fu@intel.com>

* mfenc: Avoid including codecapi.h, fix building in UWP mode with clangMartin Storsjö2020-05-272-7/+14
| | | | | | | | | | | | | Including codecapi.h and uuids.h in UWP mode doesn't define all defines properly, ending up with constructs that MSVC silently tolerates, but that clang errors out on, like this: DEFINE_GUIDEX(CODECAPI_AVEncCommonFormatConstraint); Just avoid including codecapi.h completely and hardcode the last few enum values we use from there. We already use local versions of most enums from there, due to older mingw-w64 headers being incomplete. Signed-off-by: Martin Storsjö <martin@martin.st>
* mfenc: Remove an unused includeMartin Storsjö2020-05-271-3/+1

* opusenc: add apply_phase_inv optionLynne2020-05-263-2/+4
| | | | | By popular request. Does the same as in libopusenc.
* pngdec: add ability to check chunk CRCLynne2020-05-261-0/+17
| | | | | | | | By default now, if AV_EF_CRCCHECK or AV_EF_IGNORE_ERR are enabled the decoder will skip the chunk and carry on with the next one. This should make the decoder able to decode more corrupt files because the functions which decode individual chunks will very likely error out if fed invalid data and stop the decoding of the entire image.
* mpegaudiodec_template: add ability to check CRCLynne2020-05-261-3/+17
| | | | | | A lot of files have CRC included. The CRC only covers 34 bytes at most from the frame but it should still be enough for some amount of error detection.
* apedec: add ability to check CRCLynne2020-05-261-1/+25
| | | | | | | | The CRC flag is only signalled once every few minutes but CRC is still always present so the patch uses the file version instead. CRC on 24-bit files wants non-padded samples so skip such files. Some corrupt samples may have been output before the final check depending on the -max_samples setting.

* mfenc: Fix building with clang in MSVC modeMartin Storsjö2020-05-231-0/+3
| | | | | | | | | | | | | | | Just including icodecapi.h + codecapi.h apparently misses some bits, that MSVC doesn't complain about, but Clang does. Thus add a missing header to the custom hacky include path (required for keeping ICodecAPI visible when building in UWP mode, as it is intended to). The issue in Windows SDK headers about ICodecAPI availability in UWP/app mode has been reported upstream at https://developercommunity.visualstudio.com/content/problem/1037125/icodecapi-not-visible-when-compiling-in-uwp-mode.html, and later also filed in Feedback Hub (which can't be linked to externally).

* avcodec/bsf: mention that av_bsf_send_packet() returning EAGAIN is not an errorJames Almer2020-05-221-2/+3
| | | | | | | | | | | | | | | EAGAIN is returned when input is provided but can't be consumed. The filtering process is unaffected in this case, and the function will be able to consume new input after retrieving filtered packets with av_bsf_receive_packet(). Remove the line about empty packets never failing added in 41b05b849f215b03eeb9e3608571ba47de64182a while at it. Even if it's currently the case, it unnecessarily constrains the API and could be changed in the future in case it needs to be extended. The user should always check for errors and never expect a call to never fail. Reviewed-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>
