I have a batch of dnxhd files generated from Avid projects which generate an "Unsupported: variable ACT flag" error, followed by "Adaptive color transform in an unsupported profile" warnings in ffplay and ffmpeg.
The full console output from ffplay is below. The error shows up coincident with visual effects graphics in the edit. In the example given below, the error shows up about 40 seconds into the program. The files play with no visual problems but this error crashed Tektronix Aurora quality control software that we use. The Avid export is generated using a "same as source" setting in the Avid project. If the Avid export specifies a DNXHD codec the error does not show up. I can also use the following command to re-encode the files and the error goes away: ffmpeg [INPUT] -c:v dnxhd -b:v 175M -pix_fmt yuv422p10le -map v -map a [OUTPUT] I have been told that this error is not a problem, but the people who have told me this can not state why it isn't a problem. These are final deliverable files and my concern is that they may fail on some player at some point in the future in a similar way to crashing the Tektronix Aurora software. We have a new version of the Aurora software which no longer crashes, but Tektronix has not released the details on what caused the crash to begin with. In order to make an informed decision about these files I need an understanding of the significance of the "Unsupported" variable ACT flag in a dnxhd file. Can anyone explain the significance of this error and what impact it may have on the files? Thank you. Gary PS: I realize that this output is not from the latest version of ffmpeg, but this error can also be generated with the latest version, and the subsequent changes made to the code which generates this error (https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/dnxhddec.c), don't seem to relate to this error in any way.
