[FFmpeg-user] uncompressed RGB within MXF
Hi, I see that uncompressed RGB is not supported within MXF. I know that Resolve can create 10-bit RGB but only at HD resolution. I didn't see anything relating to uncompressed RGB in the UL list in mxfenc.c and I don't have an SMPTE account to get beyond the Paywall that would let me know what RGB pixel formats are possible within MXF in a general sense. I'm assuming that there isn't some option that I'm missing out on here, it just isn't supported? $ ./ffmpeg -f lavfi -i testsrc -pix_fmt gbrp10le -c:v copy out.mxf ffmpeg version N-92260-g3cc3cb663b Copyright (c) 2000-2018 the FFmpeg developers built with gcc 7 (Ubuntu 7.3.0-27ubuntu1~18.04) configuration: libavutil 56. 20.100 / 56. 20.100 libavcodec 58. 33.102 / 58. 33.102 libavformat58. 19.102 / 58. 19.102 libavdevice58. 4.106 / 58. 4.106 libavfilter 7. 37.100 / 7. 37.100 libswscale 5. 2.100 / 5. 2.100 libswresample 3. 2.100 / 3. 2.100 Input #0, lavfi, from 'testsrc': Duration: N/A, start: 0.00, bitrate: N/A Stream #0:0: Video: rawvideo (RGB[24] / 0x18424752), rgb24, 320x240 [SAR 1:1 DAR 4:3], 25 tbr, 25 tbn, 25 tbc [mxf @ 0x56227a627880] track 0: could not find essence container ul, codec not currently supported in container Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted Stream mapping: Stream #0:0 -> #0:0 (copy) Last message repeated 1 times Best, Kieran. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
