Lynne	e8f054b095	lavu/tx: implement 32 bit fixed point FFT and MDCT 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.	5 years ago

Michael Niedermayer	3182114f88	avutil/log: Add av_log_once() for printing a message just once with a high log level Compared to ad-hoc if(printed) ... code this allows the user to disable it by adjusting the log level Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago
Wonkap Jang	f3bb59209f	avcodec/libvpxenc: add a way to explicitly set temporal layer id In order for rate control to correctly allocate bitrate to each temporal layer, correct temporal layer id has to be set to each frame. This commit provides the ability to set correct temporal layer id for each frame. Signed-off-by: James Zern <jzern@google.com>	5 years ago

Philip Langdale	88d2ccbe93	lavfi/vf_hwupload: Add support for HW -> HW transfers As we find ourselves wanting a way to transfer frames between HW devices (or more realistically, between APIs on the same device), it's desirable to have a way to describe the relationship. While we could imagine introducing a `hwtransfer` filter, there is almost no difference from `hwupload`. The main new feature we need is a way to specify the target device. Having a single device for the filter chain is obviously insufficient if we're dealing with two devices. So let's add a way to specify the upload target device, and if none is specified, continue with the existing behaviour. We must also correctly preserve the sw_format on such a transfer.	5 years ago
Lynne	a88449ffb2	lavu: add Vulkan hwcontext code 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.	5 years ago

Marton Balint	3cdc71348e	avformat/dashenc: use AV_OPT_TYPE_DICT for http_opts This changes the separator character from comma to colon, but since this option was only added recently I think it should be done for consistency with other similar options.

Wonkap Jang	b93098253e	avcodec/libvpxenc: add VP9 temporal scalability encoding option This commit reuses the configuration options for VP8 that enables temporal scalability for VP9. It also adds a way to enable three preset temporal structures (refer to the documentation for more detail) that can be used in offline encoding.

Marton Balint	15d160cc0b	avformat/udp: increase the default buffer size of a receiving socket to 384K It is a common mistake that people only increase fifo_size when they experience drops, unfortunately this does not help for higher bitrate (> 100 Mbps) streams when the reader thread simply might not receive the packets in time (especially under high CPU load) if the default 64 KB of kernel buffer size is used. New default is determined so that common linux systems can set this buffer size without tuning kernel parameters. Signed-off-by: Marton Balint <cus@passwd.hu>	5 years ago
