I have downloaded this CityAlley file, 3.5GB 7z file. Unzipped it is a 15G file with the name CityAlley_3840x2160_50fps_10bit.yuv . Trying to load it in CinGG 2021-05 AppImage does not work, it just seems to do nothing. Not even accepted as resource only. If I set the format to 368x2160p50 RGBA float, and select the file, load strategy "concatenate to existing tracks", then click "apply", a window comes saying "... format couldn't be determined, assume raw PCM , and shows audio format choices. Which obviously is not correct. No errors when started in a terminal. The "file" command does not seem to know what kind of file it is either, it just says "data". I assume that because it is raw, CinGG (or the "file" cmd) cannot determine what file it is. I have not looked into the file header. If the frame format would be known, e.g. is there in spite of raw some indication of when a new frame starts, then I presume this could be added to CinGG. Otherwise how do you know now many bytes/pixel? MatN On Tue, 15 Jun 2021 10:00:59 -0600 Phyllis Smith via Cin <[email protected]> wrote:

yeah, I think autodetection of raw yuv video is one feature of y4m format.. YUV4MPEG2 W352 H144 F25:1 Ip A0:0 C444p16 XYSCSS=444P16 XCOLORRANGE=FULL FRAME from y4m header of file I did with my patched cingg/ffmpeg.... try to manually streamconvert this yuv file with ffmpeg? like ffmpeg - i file.yuv -c:v copy -s 3680x2160 - r 50 - pix_fmt=yuv444p10le -f yuv4mpegpipe file.y4m (from memory)
If the frame format would be known, e.g. is there in spite of raw some indication of when a new frame starts, then I presume this could be added to CinGG. Otherwise how do you know now many bytes/pixel?

i hacked ffmpeg-4.4 so it exposes this list of pix_fmts for cingg to display. and now you can make huuuuge y4m files with high bit depth (10/12/14/16 and better subsampling / 422, 444) unfortunately it seems our processing of 'strict' option is broken, so i hacked out err message... from libavformat/yuv4mpegpipe muxer.. not sure if vdpau/vaapi/nvenc decoding/encoding still work, i only saw ref. to this wrapped_avframe in declink/opengl/xv *devices* (currently unused by cingg? ) and vapoursynth muxer...
