Why can't I play utvideo codec?

[arantius]

I'm editing video, with lossless intermediaries. If I try to preview the utvideo coded version before I pass it through the expensive final encoding phase, with VLC, it tells me:

Code: Select all

No suitable decoder module: VLC does not support the audio or video format "ULY2". Unfortunately there is no way for you to fix this.

But as far as I can tell ( https://github.com/videolan/vlc/commit/ ... f89#L2L906 ) support was added last December; version 2.0.8 is much newer than that. Is this optional/bleeding edge/not in normal builds? Is something else going wrong?

Please upload a short sample of such video file to either http://streams.videolan.org/upload/ or to EmbedUpload.com, the latter will upload the file for you to several other hosts and then post the link to the file here.

If needed cut it with DGsplit and read here about how to do it:

50 MB max should be enough.

This commit is only on 2.1.0. Try 2.1.0-rc1

Thanks for the suggestion Jean-Baptiste. I tried 2.1.0-rc1, and it instead says:

Code: Select all

No suitable decoder module: VLC does not support the audio or video format "ULRA". Unfortunately there is no way for you to fix this.

These files were encoded by ffmpeg with "-vcodec utvideo". If I use ffmpeg to inspect it claims it is:

Code: Select all

Stream #0:0: Video: utvideo (ULY0 / 0x30594C55), yuv420p, 1280x720, 29.97 tbr, 29.97 tbn, 29.97 tbc

This test video ( https://dl.dropboxusercontent.com/u/678 ... deo-ut.avi 15MB) also produces this error.
