94422871fc avfilter/buffersrc: limit link variance logs below debug loglevel 
The video param change check will print loglines below debug level
for each frame which is different from the inlink parameters. This
can spam the console. It is now printed at warning level once for
each param change else it is kept at debug level.

Partially addresses #10823

0d00e2e2f7 fftools/ffmpeg_dec: eliminate all remaining InputStream uses 
Previously, the demuxer would register decoder with the scheduler, using
InputStream as opaque, and pass the scheduling index to the decoder.

Now the registration is done by the decoder itself, using DecoderPriv as
opaque, and the scheduling index is returned to demuxer from dec_open().

decoder_thread() then no longer needs to be accessed from outside of
ffmpeg_dec and can be made static.
