HowTo: Encode Video for iPod Video

[endersshadow]

FXFMan: Make bitrate and maxrate both 0.

Metallinut: Take out the -bufsize 4096 argument.

[FXFman1209]

Nope

Try switching Buffer Size to 0 and Audio Bitrate to 128.

[FXFman1209]

Alright...

Same thing.

[endersshadow]

You didn't set maxrate and bitrate to 0, as well

Here's what the issue is: That version of Vive was made w/ the older ffmpeg which dealt with rates as kb/s. Now, it deals with them as b/s, so it is now giving you underflow errors.

[FXFman1209]

Woops. I'm sorry, I set those to 0 on another test. Here is the output when ALL of them have been set to 0.

Now that's and new one!

It appears that it's a bit of a problem w/ a yuv as an input. Cut and paste this command into your terminal:

ffmpeg -i "/home/fxfitz/multimedia/videos/psych/Psych.S01E15.DSR.XviD-ORENJi.avi" -f mp4 -vcodec mpeg4 -b 700k -aspect 4:3 -r 23.98 -s 320x240 -acodec aac -ar 48000 -comment "Encoded by Vive" "/home/fxfitz/test.mp4"

[FXFman1209]

Unknown codec: aac.

[endersshadow]

Unknown codec: aac.

My fault...habit made me type aac instead of ac3...sorry!

P.S.-This for an iPod? If so, use mp3, not ac3.

[FXFman1209]

Awesome! It's encoding!

Alright, so, how would I get this to work all the time with Vive? Or do I have to command line it all the time?

PS. And what exactly was the problem?? yuv??
