Support transcoding matching for fourcc (AVI) codes

[Former user]

Is it possible to get vCodec="DX50" supported, as AVI files encoded using DX50 cannot be transcoded currently using the profile.xml config. you must transcode ALL AVI files to select this file type which is overkill.

XBOX360 does not support DX50 at this time, and transcoding is required.

Is there any way to set up serviio to accept any information in the vCodec field instead of checking against a pre-defined list (to where you can set vCodec="" to whatever ffmpeg reports as the codec for the file)? or is this required for some fancy internal stuff?

Ideally it might be better to be able to match on the FourCC code inside the AVI (using something like vCodec="AVI,DX50") which could help for newer Sony 2012 firmwares which natively play Xvid but not DivX.

It probably won't be vCdec matching (still mpeg4), but fourCC code, similar to isom

Not extremely knowledgeable on this, but whatever solution works that you find to be the best implementation.

So I have one AVI with DX50 and it plays without transcoding on the XBox.

Do you have more dx50 files that don't play?

[Petr Nejedly]

The matcher has been implemented (using vFourCC Matches attribute, supporting comma-separated list of fourcc values).

It's to be decided how to update current profiles during the beta testing.

I have whole seasons of dx50 files that don't play.

[Former user]

Has this actually been implemented? I can hardly find any documentation or examples at all on vFourCC. I have files that are detected as DX50 with ffmpeg, but when I attempt to target them, they do not transcode. Am I doing something wrong?

Transcodes :<Matches container="avi" vCodec="mpeg4" /> Doesn't transcode: <Matches container="avi" vCodec="mpeg4" vFourCC="DX50" />

[Former user]

Ahh, I figured it out. The FourCC codes have to be all lowercase without spaces in the CSV list. It may be helpful to add that to the wiki for the vFourCC section since FourCC codes are normally written in caps, and that is the way ff-mpeg displays them as well.
