2022-11-04swscale: aarch64: Fix yuv2rgb with negative stridesMartin Storsjö
Treat the 32 bit stride registers as signed. Alternatively, we could make the stride arguments ptrdiff_t instead of int, and changing all of the assembly to operate on these registers with their full 64 bit width, but that's a much larger and more intrusive change (and risks missing some operation, which would clamp the intermediates to 32 bit still).

2022-11-04avcodec/atrac3plus: reorder channels to match the output layoutJames Almer
The order in which the channels are coded in the bitstream do not always follow the native, bitmask-based order of channels both signaled by the WAV container and forced by this same decoder. This is the case with layouts containing an LFE channel, as it's always coded last. Fixes ticket #9964.

2022-11-04avcodec/aacdec: fix parsing streams with channel configuration 11James Almer
Set the correct amount of tags in tags_per_config[]. Also, there are no channels that correspond to a side element in this configuration, so reflect this in the list of known/supported channel layouts.

2022-09-25lavc/videotoolbox: do not pass AVCodecContext to decoder output callbackAnton Khirnov
The opaque parameter for the callback is set in videotoolbox_start(), called when the hwaccel is initialized. When frame threading is used, avctx will be the context corresponding to the frame thread currently doing the decoding. Using this same codec context in all subsequent invocations of the decoder callback (even those triggered by a different frame thread) is unsafe, and broken after cc867f2c09d2b69cee8a0eccd62aff002cbbfe11, since each frame thread now cleans up its hwaccel state after decoding each frame. Fix this by passing hwaccel_priv_data as the opaque parameter, which exists in a single instance forwarded between all frame threads. The only other use of AVCodecContext in the decoder output callback is as a logging context. For this purpose, store a logging context in hwaccel_priv_data.

2022-09-24avformat/cafenc: derive Opus frame size from the relevant stream parametersJames Almer
Use the stream duration as last resort, as an off-by-one result of the "st->duration / (caf->packets - 1)" calculation can break playback on some devices. Also, don't write the sample_rate value propagated by encoders like libopus. The sample rate of the audio fed to it is irrelevant after being encoded. Fixes ticket #9930.

2022-09-20avcodec/arm/sbcenc: avoid callee preserved vfp registersJames Cowgill
When compiling FFmpeg with GCC-9, some very random segfaults were observed in code which had previously called down into the SBC encoder NEON assembly routines. This was caused by these functions clobbering some of the vfp callee saved registers (d8 - d15 aka q4 - q7). GCC was using these registers to save local variables, but after these functions returned, they would contain garbage. Fix by reallocating the registers in the two affected functions in the following way: ff_sbc_analyze_4_neon: q2-q5 => q8-q11, then q1-q4 => q8-q11 ff_sbc_analyze_8_neon: q2-q9 => q8-q15 The reason for using these replacements is to keep closely related sets of registers consecutively numbered which hopefully makes the code more easy to follow. Since this commit only reallocates registers, it should have no performance impact.

original values Instead of the potentially adjusted ones. Otherwise, if config_props() is called again and if using force_original_aspect_ratio, the already adjusted values could be altered again. Example command line scale=size=1920x1000:force_original_aspect_ratio=decrease:force_divisible_by=2 user value 1920x1000 -> 1920x798 on init_dict() -> 1918x798 on frame change when eval_mode == EVAL_MODE_INIT, which after e645a1ddb9 could be at the very first frame.

2022-09-06lavc/pthread_frame: avoid leaving stale hwaccel state in worker threadsAnton Khirnov
This state is not refcounted, so make sure it always has a well-defined owner. Remove the block added in 091341f2ab5bd35ca1a2aae90503adc74f8d3523, as this commit also solves that issue in a more general way.
