[vlc-devel] [PATCH] chromecast: fix regression

[Shaleen Jain]

Before commit ec61edc0d0292ab37bb1dbafb23a8aed49e966bb
chromecast depended on vlc_sout_renderer_GetVcodecOption
to signal the codec selected to transcode to.
Achieve that by introducing an output parameter
where the codec used is written.
