In need of .dxa conversion help

Hello. Kind of a last ditch effort to convert some dxa files to basically any other video format. Tried searching everywhere, but thought I might post in hopes that someone might be able to help. Thank you.

You will have to work out how to invoke FFMPEG to transcode to your target format...

@digitall *From* DXA, not *to*.

@clone2727: Thank you for the brusque response, but I am aware of that...

My point was that if FFMPEG has DXA encode support, it would likely have DXA decode support and thus be capable of transcoding from DXA to any other video format.

A quick Google search shows that I was correct in this assumption:

Yeah I did stumble across that, but it's completely foreign to me. I don't even know where to begin.

I figured out how to do basic conversions in command prompt, but its not letting me convert .dxa to .mpeg. it keeps saying no such file or directory. Could someone tell me the code I would need to punch in for ffmpeg? Thanks again. I was just doing ffmpeg -i a.dxa -ar 22050 a.mp4

OK... I used the DXA videos from our old Broken Sword Video Pack:

Firstly, check you can playback a video with your FFMPEG. I used "ffplay SEWER.dxa" to prove this.

If your version does not work, get the newest version from the FFMPEG website.

Secondly, I just used the following to transcode this to MP4:
ffmpeg -i SEWER.dxa sewer.mp4

You may need to experiment with options as per the documentation to get the correct output format you want and you may need a video filter to resize, change colorspace or other parameters if your desired format only supports certain options.

Hmm it's showing up as "invalid data found when processing input" - so i assume my files are messed up.
