ffmpeg.exe & ffprobe.exe: -codecs » Invalid Flags for 9 Codecs

[Thomas]

Hello
Thank you very much for your great and useful work!

Summary of the bug:
The codecs listing

% ffprobe.exe -v quiet -codecs
% ffmpeg.exe -v quiet -codecs

declares those Flags in the header:

Codecs:
 D..... = Decoding supported
 .E.... = Encoding supported
 ..V... = Video codec
 ..A... = Audio codec
 ..S... = Subtitle codec
 ...I.. = Intra frame-only codec
 ....L. = Lossy compression
 .....S = Lossless compression
 -------

Now, ffmpeg.exe & ffprobe.exe lists the following 9 Codecs with invalid Flags because (according to the codecs header) at position 3, it is impossible to have a 'D' Flag:

..D... bin_data             binary data                               
..D... dvd_nav_packet       DVD Nav packet                            
..D... epg                  Electronic Program Guide                  
..D... klv                  SMPTE 336M Key-Length-Value (KLV) metadata
..D... mpegts               raw MPEG-TS stream                        
..D... otf                  OpenType font                             
..D... scte_35              SCTE 35 Message Queue                     
..D... timed_id3            timed ID3 metadata                        
..D... ttf                  TrueType font

The third column indicates the media type. Although not shown in the header description, D stands for Data. T for attachment is the other undocumented media type.

Thank you for your answer!,

The third column indicates the media type.

T for attachment is the other undocumented media type.

Why don't you just extend the header description, so that it will never get questions again?

It would be even useful for other / new developers because they do not have to use reverse engineering to understand undocumented flags :-)

Thanks a lot, kind regards,

Does it make sense not to fix this small issue and display all information to the user?
It helps a lot to get useful information right from the tool and not to have to google for this kind of question :-)

Thanks a lot, kind regards,
