* avcodec/v4l2: set sizeimage param for non-raw buffers [fixes #6716]Jorge Ramirez-Ortiz2017-10-04
| | | | | | | | | | | | | | | | | Some V4L2 drivers fail to allocate buffers when sizeimage is not set to a max value. This is indeed the case for s5p-mfc [1] Most drivers should be able to calculate this value from the frame dimensions and format - or at least have their own default. However since this work around should not impact those drivers doing the "right thing" this commit just provides such a default. The calculations were extracted from the v4l2 driver used to develop the ffmpeg v4l2_m2m support [2]. See venc.c and vdec.c [1] linux.git/drivers/media/platform/s5p-mfc [2] linux.git/drivers/media/platform/qcom/venus/

| | | | | | | | | It is to fix https://trac.ffmpeg.org/ticket/6677. Actucally it is a regression of commit 99e07a4453732058df90885f80b3db3b4f37cb3c which always inserts a dummy frame when decode the first key field picture.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idct32x32 function actually pushed d8-d15 onto the stack even though it didn't clobber them; there are plenty of registers that can be used to allow keeping all the idct coefficients in registers without having to reload different subsets of them at different stages in the transform. After this, we still can skip pushing d12-d15.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idct32x32 function actually pushed q4-q7 onto the stack even though it didn't clobber them; there are plenty of registers that can be used to allow keeping all the idct coefficients in registers without having to reload different subsets of them at different stages in the transform. Since the idct16 core transform avoids clobbering q4-q7 (but clobbers q2-q3 instead, to avoid needing to back up and restore q4-q7 at all in the idct16 function), and the lanewise vmul needs a register in the q0-q3 range, we move the stored coefficients from q2-q3 into q4-q5 while doing idct16. While keeping these coefficients in registers, we still can skip pushing q7.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For this case, with 8 inputs but only changing 4 of them, we can fit all 16 input pixels into a q register, and still have enough temporary registers for doing the loop filter. The wd=8 filters would require too many temporary registers for processing all 16 pixels at once though.

| | | | | | | | | | | | | | | | | | This was broken by 4e528206bc4d968706401206cf54471739250ec7 - the webp decoder was assuming that it could set the output pixfmt of the vp8 decoder directly, but after that change it no longer could because ff_get_format() was used instead. This adds an internal get_format() callback to webp use of the vp8 decoder to override the pixfmt appropriately.
