This patch set goes back to using request_sample_fmt. ffmpeg and ffplay are
modified to set AVOptions prior to calling av_find_stream_info() so that the
decoder will be initialized with the user-requested sample format.
Justin Ruggles (5):
Add float_interleave() to FmtConvertContext with x86-optimized
versions.
Add request_sample_fmt field to AVCodecContext.
Add APIchanges entry for request_sample_fmt.
Add support for request_sample_format in ffmpeg and ffplay.
Add floating-point sample format support to the ac3, eac3, dca, aac,
and vorbis decoders.
