Fix transcode pipeline when using passthrough for the video track, for
example when using chromecast which doesn't try to convert the video
track.

Thus, it also fixes the playback of correct h264 stream on chromecast.

This was a regression from 553a5da7
due to patch transcode-add-support-for-multiple-venc-parameters.
