I am having fun and games getting the proxy generator to do what I want. The main problem is caused by the file having a 16 channel audio stream. Rendering seems to work fine for this, but it will not produce a proxy file.

I have managed to make ffmpeg play nice with the file, but when I try and put it into the proxy clip generator settings it fails.


The following works from the terminal:

Code: Select all

ffmpeg -i input.mov -f mpegts -map 0:0 -map 0:1 -map 0:1 -map 0:1 -map 0:1 -map 0:1 -map 0:1 -map 0:1 -map 0:1 -map_channel 0.1.0:0.1 -map_channel 0.1.1:0.2 -map_channel 0.1.2:0.3 -map_channel 0.1.3:0.4 -map_channel 0.1.4:0.5 -map_channel 0.1.5:0.6 -map_channel 0.1.6:0.7 -map_channel 0.1.7:0.8 -vcodec mpeg2video -g 5 -deinterlace -s 480x270 -vb 400k -acodec libmp3lame -ac 2 -ab 128k -ar 48000 output.ts

when I put it into the proxy generator as:

Code: Select all

-f mpegts -map 0:0 -map 0:1 -map 0:1 -map 0:1 -map 0:1 -map 0:1 -map 0:1 -map 0:1 -map 0:1 -map_channel 0.1.0:0.1 -map_channel 0.1.1:0.2 -map_channel 0.1.2:0.3 -map_channel 0.1.3:0.4 -map_channel 0.1.4:0.5 -map_channel 0.1.5:0.6 -map_channel 0.1.6:0.7 -map_channel 0.1.7:0.8 -vcodec mpeg2video -g 5 -deinterlace -s 480x270 -vb 400k -acodec libmp3lame -ac 2 -ab 128k -ar 48000

it fails with the error:

aac, Copyright (c) 2000-2014 the Libav developers
built on Aug 11 2014 23:12:18 with gcc 4.8 (Ubuntu 4.8.2-19ubuntu1)
Unrecognized option 'map_channel'.
Error splitting the argument list: Option not found

I'm guessing I am getting something blindingly obvious wrong, but cant figure out what it is.
