Trying to load it in CinGG 2021-05 AppImage does not work, it just<br>
seems to do nothing. Not even accepted as resource only. If I set the<br>
format to 368x2160p50 RGBA float, and select the file, load strategy<br>
"concatenate to existing tracks", then click "apply", a window comes<br>
saying "... format couldn't be determined, assume raw PCM , and shows<br>
audio format choices. Which obviously is not correct.<br>
<br>
No errors when started in a terminal. <br>
The "file" command does not seem to know what kind of file it is<br>
either, it just says "data".<br>
<br>
I assume that because it is raw, CinGG (or the "file" cmd) cannot<br>
determine what file it is.

If the frame format would be known, e.g. is there in spite of raw some<br>
indication of when a new frame starts, then I presume this could be<br>
added to CinGG. Otherwise how do you know now many bytes/pixel?<br>
