FFmpeg API has changed 0.9

[Illico]

FFmpeg documentation

The API for stream mapping has changed for releases 0.9 and above or API level - libavcodec - 53. 42. 0 and above.
New options are applied per stream separated by a colon with the stream specifier and option following. For ex:

-option:stream_type(v,a):stream_specifier(0,1,2,etc) - v for video, a for audio
-codec:v:0 vob
-codec:a:0 ac3 (ac3 encoding for audio stream 1)
-b:a:0 448k (448k rate encoding for audio stream 1)
-ac:1 2 (2 channel audio for stream 2)
-codec:v:0 copy

This new format is used for almost all options dealing with streams now, there are some alias' in place for the changeover (ex: vcodec option) but may be removed at anytime in the future.

Also it seems command order is now important. (Sony Aspect Ratio workaround doesn't work : viewtopic.php?f=11&t=2956&start=30#p27617)

Zip, do you plan to update the serviio/ffmpeg wrapper?

I will at some point. There are still people using older ffmpeg versions so will keep the older syntax in place.
