2019-09-16avcodec/ttaenc: Fix undefined shiftAndreas Rheinhardt
ttaenc contained (1 << unary) - 1 as an argument for a function expecting an unsigned int. unary can be as big as 31 in this case. The type of the shift and the whole expression is int, because 1 fits into an integer, so that the behaviour is undefined if unary == 31 as the result of the shift can't be represented in an int §. Subtraction by 1 (which makes the result of the whole expression representable in an int) doesn't change that this is undefined (it usually leads to signed integer overflow which is undefined, too). The solution is simple: Make 1 unsigned to change the type of the whole expression to unsigned int (as the function expects anyway). Fixes ticket #8153. §: This of course presupposes the common int range of -2^31..2^31-1 Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2019-09-16avcodec/videotoolboxenc: fix encoding frame crash on iOS 11sharpbai
On iOS 11, encoding a frame may return error with log "Error encoding frame 0", which means vtenc_output_callback is called with status=0 and sample_buffer=NULL. Then the encoding session will be crashed on next callback wether or not closing the codec context. Let us look through the link below introducing VTCompressionOutputCallback, https://developer.apple.com/documentation/videotoolbox/vtcompressionoutputcallback?language=objc "status=0" (noErr) means compression was successful. "sampleBuffer=NULL" means the frame was dropped when compression was successful (status=0) or compression was not successful (status!=0). So we should not set AVERROR_EXTERNAL on "status=0" and "sample_buffer=NULL" as it is not a error. The fix is that we only set AVERROR_EXTERNAL with status value non zero. When sample_buffer is NULL and status value is zero, we simply return with no other operation. This crash often occurs on iOS 11 for example encoding 720p@25fps.

A threshold of 1 is sufficient for simple_dump_cut.webm, 10 is used just to be sure the next truncated file doesnt cause the same issue Obvious alternative fixes are to simply accept that the file is broken or to write some advanced error concealment or to simply accept that the decoder wont stop at the end of input.

* FFmpeg retrieves a packet from the bitstream * It attempts to get an input buffer (from its own list or by dequeuing one from the driver) * If no input buffer is found, the bitstream packet is dropped instead of scheduled for trying again later It's an issue that showed especially at high speeds (like using `-f null -` as output parameters).

2019-09-11avcodec/v4l2_buffers: read height/width from the proper contextAman Gupta
Frames are generally dequeued into capture buffers, so using the output properties here was incorrect. It happened to work fine for decoding, since the output/capture buffers have the same dimensions. For the v4l2 scaler, the dimensions can be different between output and capture. Using the buffer's associated context makes this code work correctly regardless of where the frame is coming from. Signed-off-by: Aman Gupta <aman@tmm1.net>

2019-09-11opusdsp: adjust and optimize C function to match assemblyLynne
The C and asm versions behaved differently _outside_ of the codec. The C version returned pre-multiplied 'state' for the next execution to use right away, while the assembly version outputted non-multiplied 'state' for the next execution to multiply to save instructions. Since the initial state when initialized or seeking is always 0, and since C and asm versions were never mixed, there was no issue. However, comparing outputs directly in checkasm doesn't work without dividing the initial state by CELT_EMPH_COEFF and multiplying the returned state by CELT_EMPH_COEFF for the assembly function. Since its actually faster to do this in C as well, copy the behavior the asm versions use. As a reminder, the initial state 0 is divided by CELT_EMPH_COEFF on seek and init (just in case in the future this is changed, its technically more correct to init with CELT_EMPH_COEFF than 0, however when seeking this will result in more audiable pops, unlike with 0 where the output gets in sync over a few samples).
