It's required to be non-zero since
cc58300e

There's no point in keeping them separate.

Those are reserved for the libs.

They were replaced by (de)muxer private options.

Deprecate AVFormatContext.loop_output.

Deprecate AVFormatContext.loop_input.

That is, unless the caller explicitly asks for them.

Prevents conflict between e.g. the 'loop' option in img2 demuxer and
'loop' flag in AVCodecContext.

The build system doesn't use lib.exe any longer, and therefore this
can be simplified.

The copy regression test script is unused, bash-specific and did
not even work properly when it was originally committed.

libavcodec/libvo-amrwbenc.c:37:5: warning: missing braces around initializer

Parse the extension flag bit when reading the MPEG4 AudioSpecificConfig.

This has nothing to do with SBR/PS contradictory to what was noted when it was removed.

Make it clear that open_inputs/open_outputs are updated only if non-NULL.
