Ok, good to know. My guess is probably Austria? > Does the output file play on Windows with the > AJA codec installed? Yes it does! So great job! =) Your fix now can play r10k (Little Endian) files in Windows on a PC using the AJA Codec. With your fix in FFmpeg, I can now take the r10k (little endian) lossless video and convert it to FFV1 (lossless): I call that "r10kToFFV.avi). However, there is an issue with converting the FFV1 back to the original r10k (little endian) format: Using the command: ffmpeg -i r10kToFFV.avi -pix_fmt gbrp10le -vcodec r10k -c:a copy FFVTor10k.avi -f framemd5 -an FFVTor10k.framemd5 Where r10kToFFV.avi is the FFV1 file (which now holds the lossless compressed r10k video) I get the warning message: "Incompatible pixel format 'gbrp10le' for codec 'r10k', auto-selecting format 'rgb48le' [swscaler @ 0000000002bfcfe0] full chroma interpolation for destination format 'rgb48le' not yet implemented" You can see that in my last mail message. The framemd5's do NOT match going from r10k -> FFV1 -> r10k. Why is that?
