Hi, I had a look at different options on how to fix the regression, though I am not sure what I arrived at is what you had in mind. I tried to read up a bit on opus as well and I assume you are talking about the frame length coding allowing coding of zero-byte frames? If so, my understanding

I have limited duplicated code by making the decoder calling the parser. An option would be to leave all common code to dolby_e.c and move decoding to dolby_edec.c, but that would require either to duplicate 3 "very-internal" functions (skip_input/parse_key/convert_input) 3x times instead of twic

Re: [FFmpeg-devel] [PATCH] Moves yuv2yuvX_sse3 to yasm, unrolls main loop and other small optimizations for ~20% speedup.

Apologies for this: when I added mmx to the yasm file, I added a macro for the stores selecting mova for mmx and movdqu for the others. if cpuflag(mmx) evaluates to true for all architectures so I replaced it with if notcpuflag(sse3). The alignment in the checkasm test has been changed to 8 from 3
