Did I already ask why you are using ffvhuff? Isnt't this an ancient codec without specification or similar? And not even tested by the archiver community? No, you didnt ;) I/we use this ffvhuff codec as internal working format (SD/HD/2K/4K sources). The final archive format is generated from

Re: [FFmpeg-user] V210 is a packet format but ffmpeg shows always yuv422p10le (planar?) - or how to read a V210.raw stream with ffmpeg?

Very, very generally: No, this is the reason why a decoder is needed: Some applications produce an incorrect framesize for a given resolution. But in the case of a given application, the framesize has to be constant for a given resolution: If it is not, the file cannot be read. (And the

Re: [FFmpeg-user] Numerical histogram output for checking typical broadcast ranges (16-235)

I am very new in using the histogram filter. (http://ffmpeg.org/ffmpeg-filters.html#histogram) Is it possible to dump the video level values from which the histogram graph is drawn into numeric values (textfile dump) to check if a video has levels inside the broadcast ranges (16-235/94-940)?

You can manually specify these settings to force them being set with these parameters: -color_primaries 5 -color_trc 1 -colorspace 6 What does not work as far as I know in ffmpeg is to actually get these settings from the source video, even if ffprobe detects them. Regards, Marton Thank

(I don't think FFmpeg reads from the output file if that was your question.) That WAS the question ;) I thought you meaned FFmpeg (reads the source file of course) and writes the target file and reads it (for filechecking or something) - And that would be the cause for the slow merging speed

Don't know if its relevant but your coding parameters are slightly different to the one's I use for D10, and I wonder if this affects the automatic metadata insertion.. -flags +ildct+ilme+low_delay Well ilme seems kind of redundant for I frame only coding but probably harmless. -tag:v mx5p

But let me try it differently: You have an input file with a logarithmic colour space that is not supported by FFmpeg. If you are sure that you know what you are doing, you can of course use FFmpeg to compress your raw data (I believe ffv1 was tested much better already but this is not really

We've encountered something similar when transcoding FFV1 over the network. So we used framemd5 not to verify FFV1's losslessness, but to validate that the transcoding goes error-free :) FFmpeg's framemd5 became *the* feature for professional video preservation. So, thanks again for all your
