Say i have a movie with multipule embedded audio tracks, can i get MEncoder or FFMpeg to search and use a specific track based on its type?

My use is that i need to always USE the 2 Channel track instead of the 5.1

(its for handheld devices)

what im looking for:

Is it possible to have either to find that track to use befor downmixing the 5.1?

My main issue is that if i use 5.1 on some movies for what ever reason all main audio comes out of the Left channel.

WELL with a little help from dolby labs (google power!)
i was able to find a FORSURE test video for surroundsound.

http://www.dolby.com/us/en/consumer/tec ... nload.html

Downloaded the MP4 Large DOWNLOAD

This for sure ill be using for testing going forward.

Also confirmed my setup for Headphones!

Code: Select all

-channels 6 -af pan=2:1:0:0:1:1:0:0:1:1:1:1:1 lavcresample=48000
"all lefts go to left all rights go to right, center in both, sub in both.

Manually from TRANSCODE folder you can select the right one but automatically it is not possible.

yeah that's what i thought ExSport... so i just took the 5.1 and down-mixed it to 2 channel in the CONF... i had to read a lot of FFMpeg and Mencoder pages to find it lol

When you will browse to ##TRANSCODE## folder, you are able to play your 2.0 file without transcoding and reading anything ;)

I tried some of the preconfig'd ##transcode## options some of them gave me a "video could not be played" on my device.

Then debug.log in trace mode will help with description what you did and what didn't worked (for better understanding and searching in log) 8-)
