I suppose that would be the best option, yes. However, metadata comes in all kinds of shapes, so it's not easy to map arbitrary metadata (that any filter can generate) to a meaningful output format, in particular when the result should be CSV. In particular, such output should be tidy [1]. For instance, you don't want to output "frame, key, value" with lines "1, si, 53.999", but rather "frame, si, ti". Such transformations to useful/parsable output must be done in the filter itself, not vf_metadata … [1]: https://cran.r-project.org/web/packages/tidyr/vignettes/tidy-data.html _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
