2019-09-24avcodec/cbs_h264: Automatically free SEI payload on errorAndreas Rheinhardt
If adding an SEI message to an access unit fails, said SEI message was not touched, so that the caller had to free any data associated with it that might need to be freed. But given that ff_cbs_h264_add_sei_message can simply call cbs_h264_free_sei_payload, one can easily free the content of the SEI payload. This fixes a memleak when inserting a user data unregistered string for h264_metadata fails. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

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.
