[FFmpeg-devel] [PATCH 1/2] avcodec/libx264: Don't unnecessarily add in-band extradata

The check here is meant to check for whether avcintra-class option
(default value -1) has been set; yet it checks for the x264_param_t
value where 0 is the default value (treated as "no avcintra-mode"
by x264). This meant that in-band extradata has been added unnecessarily
when using global headers; furthermore, the first output packet
had two x264 SEIs.

This would have been found ages ago if we could test external
components.
