* avformat/avformat: Update av_read_frame() documentationAndreas Rheinhardt2020-03-29
| | | | | | | | | | | | | This commit updates the documentation of av_read_frame() to match its actual behaviour in several ways: 1. On success, av_read_frame() always returns refcounted packets. 2. It can handle uninitialized packets. 3. On error, it always returns blank packets. This will allow callers to not initialize or unref unnecessarily.

* avcodec/avcodec, avpacket: Return blank packet on av_packet_ref() failureAndreas Rheinhardt2020-03-28
| | | | | | | | | | | | Up until now, it was completely unspecified what the content of the destination packet dst was on error. Depending upon where the error happened calling av_packet_unref() on dst might be dangerous. This commit changes this by making sure that dst is blank on error, so unreferencing it again is safe (and still pointless). This behaviour is documented.

* lavu/tx: implement 32 bit fixed point FFT and MDCTLynne2020-02-13
| | | | | | | | | | | | | | | | | | | | Required minimal changes to the code so made sense to implement. FFT and MDCT tested, the output of both was properly rounded. Fun fact: the non-power-of-two fixed-point FFT and MDCT are the fastest ever non-power-of-two fixed-point FFT and MDCT written. This can replace the power of two integer MDCTs in aac and ac3 if the MIPS optimizations are ported across. Unfortunately the ac3 encoder uses a 16-bit fixed point forward transform, unlike the encoder which uses a 32bit inverse transform, so some modifications might be required there. The 3-point FFT is somewhat less accurate than it otherwise could be, having minor rounding errors with bigger transforms. However, this could be improved later, and the way its currently written is the way one would write assembly for it. Similar rounding errors can also be found throughout the power of two FFTs as well, though those are more difficult to correct. Despite this, the integer transforms are more than accurate enough.

* lavu: add Vulkan hwcontext codeLynne2020-02-04
| | | | | | | | | | This commit adds the necessary code to initialize and use a Vulkan device within the hwcontext libavutil framework. Currently direct mapping to VAAPI and DRM frames is functional, and transfers to CUDA and native frames are supported. Lets hope the future Vulkan video decode extension fits well within this framework.

* avutil: add ROI (Region Of Interest) data struct and bump versionGuo, Yejun2019-01-17
| | | | | | | | | | | | | | | The encoders such as libx264 support different QPs offset for different MBs, it makes possible for ROI-based encoding. It makes sense to add support within ffmpeg to generate/accept ROI infos and pass into encoders. Typical usage: After AVFrame is decoded, a ffmpeg filter or user's code generates ROI info for that frame, and the encoder finally does the ROI-based encoding. The ROI info is maintained as side data of AVFrame. Signed-off-by: Guo, Yejun <yejun.guo@intel.com> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* avformat: add fields to AVProgram/AVStream for PMT change trackingAman Gupta2018-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | These fields will allow the mpegts demuxer to expose details about the PMT/program which created the AVProgram and its AVStreams. In mpegts, a PMT which advertises streams has a version number which can be incremented at any time. When the version changes, the pids which correspond to each of it's streams can also change. Since ffmpeg creates a new AVStream per pid by default, an API user needs the ability to (a) detect when the PMT changed, and (b) tell which AVStream were added to replace earlier streams. This has been a long-standing issue with ffmpeg's handling of mpegts streams with PMT changes, and I found two related patches in the wild that attempt to solve the same problem: The first is in MythTV's ffmpeg fork, where they added a void (*streams_changed)(void*); to AVFormatContext and call it from their fork of the mpegts demuxer whenever the PMT changes. The second was proposed by XBMC in https://ffmpeg.org/pipermail/ffmpeg-devel/2012-December/135036.html, where they created a new AVMEDIA_TYPE_DATA stream with id=0 and attempted to send packets to it whenever the PMT changed.
