Is there something special you need to compile into ffmpeg in order for it to read the fifos?

I've been having the same problem. I'm trying to get a version off ffmpeg with aac compiled into it, to work with the mythtranscode fifos.

The ffmpeg version 0.4.9-pre1, build 4754 seems to work properly, but is missing aac.

When I download ffmpeg-0.4.9-pre1 source, and try and build adding aac, the build does not work at all with the fifos.

It exhibits the same behavior that you are experiencing. I did have to downgrade my copy of nuvexport to the nuvexport-0.2-0.20050317.cvs package, as the newer 20051117 build was dying on yuvdenoise errors.

In case your wondering why so much work for aac, it's so I can encode for my iPod Video.

Mythtranscode doesn't talk to ffmpeg -- nuvexport is what sets up the two processes. nuvexport *does* check for ffmpeg errors. If it's not trapping them, I need someone to email me the error so I can add it in.

I solved half the problem.  I was running with a ffmpeg release from
September of this year.  When I rolled back to the March version the
"-hq" error went away. The yuvdenoise problem is still there, though.

Can't you just check for the exit status and bail if it's non-zero?
With the later version, ffmpeg quits immediately but nuvexport just sits
there and waits and waits....

See my previous email for the exact output when I ran the command at the
CLI.


I've been strugling to get nuvexport to create an xvid today and ran into some of the same problems with the -hq option with ffmpeg and also the -4mv option.
Using transcode I got a "Audio format not supported by import module".

Maybe it would be a good idea tho document the exact versions of ffmpeg, transcode, yuvdenoise that were tested with nuvexport and their configure build options.
