#1534: report on ffv1 version and slices -------------------------------------+------------------------------------- Reporter: dericed | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: Keywords: | unspecified Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Summary of the bug: Since ffv1 version 3 may someday become the default there should be a way to identify whether an ffv1 encoding is version 1, or 3 (or 0). Currently the version isn't reported either during encoding or with ffprobe -show_streams. How to reproduce: Produce ffv1 encodings with version 1 and version 3.

The specifications for the ffv1 header are here: http://ffmpeg.org/~michael/ffv1.html#toc-Subsection-4.3. If version >1 it may be useful to report the minor_version as well. At the moment I can't think of a reason to need to report things like coder_type and number of slices but it may be nice. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1534> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
