Author: Mans Rullgard <[email protected]> Committer: Mans Rullgard <[email protected]> Date: Sun Jul 17 16:02:33 2011 +0100 lavf: do not set codec_tag for rawvideo If the demuxer did not set a codec_tag, there is none and inventing one makes no sense. This change stops the rawvideo "decoder" over-writing user-supplied pixfmt with one derived from the codec_tag. The pixfmt-codec_tag-pixfmt round-trip is lossy since several pixfmts map to the same codec_tag. This fixes fate-lavf-pixfmt with avfilter disabled.
