It is found in some 8svx files (e.g. ones created by SoX).
Currently the decoder reuses the 8svx functions because we already have
handling of a single large planar packet for the compressed 8svx codecs.

This enables the user (i.e. avconv) to automatically convert to the supported
sample format if needed.

This matches the output sample format and the range of the output values.

the user is not required to set bit_rate

This is useful if sending multicast data on a host with
multiple interfaces.

There are no reason for "if (c_valid) { ... }" to appear before
"if (b_valid) { ... }".

The current code is a generalization of the earlier progressive MV
prediction code. This was supposed to predict MVs for both interlaced
and progressive pictures. But the interlaced MV prediction is buggy
and works mostly by luck.

This partially fixes interlaced MV prediction.

The return value ret isn't an error code that can be passed
to ERR_error_string().

This makes the error messages printed actually contain useful
information.

Found with asan and the venerable 1-dog.avi sample.

'size' is populated by functions returning int64_t and int that return
negative error codes.

Bug introduced in 84ad31ff.
Thanks to Uoti Urpala for finding it.

Filenames are brittle across renames and add no useful information.

this fixes a crash when cycling audio streams if the spectrograph is
displayed.
