According to API docs avdevice_list_devices(), avdevice_list_input_sources()
and avdevice_list_input_sinks() should return the number of autodetected
devices on success. This is redundant with AVDeviceInfoList->nb_devices so it
was not noticed earlier that none of the underlying device list functions work
like that.
Let's fix it in generic code to make it in line with the API docs.
Fixes ticket #9820.

This is a per-file input option that adjusts an input's timestamps
with reference to another input, so that emitted packet timestamps
account for the difference between the start times of the two inputs.
Typical use case is to sync two or more live inputs such as from capture
devices. Both the target and reference input source timestamps should be
based on the same clock source.
If either input lacks starting timestamps, then no sync adjustment is made.

This limit is possibly not reachable due to other restrictions on buffers but
the decoder run table is too small beyond this, so explicitly check for it.

Data does not have to be decrypted in 16-byte blocks for AES-CTR mode, so
existing buggy code can be hugely simplified.

This resulted in the wrong column/row being chosen.
This can be seen best when using xfade on streams with transparency.
For example: in case of a slideleft transition, the first column from
the first input will overwrite the first column of the second stream
throught the transition.
