i got this idea from postresql, a very small sql database server
i see ffmpeg is broken down into optimized asm libraries for embedding
in c etc programs, and i know a few things about asm, ie, hardware
registers on cpu+, pump in data into a register, get data out, think
it goes down the system

Currently width_align and height_align are zero when encoding with mjpeg_qsv

This is now the working version from my last patch.
Description:
This patch unify vf_blackdetect with af_silencedetect. Now the logging
prints black_start and black_end in separate lines. This is the same
behavior like af_silencedetect and it is also more useful for monitoring
streams.
Is it ok,
Please forget the last patch! Something is not working right.
Sorry!

Muxers can check AVCodecParameters.initial_padding for the

side data from the last packet for the encoder padding.
This change also fixes the first_discard_sample calculation

libmp3lame adds the 528 + 1 only to have mp3dec subtract it, so I'm not
sure why that's done. IIUC start_skip_samples is the mechanism that
actually accounts for the extra delay when decoding.
