1 FFmpeg's bug/feature request tracker manual
2 =================================================
9 FFmpeg uses Trac for tracking issues, new issues and changes to
10 existing issues can be done through a web interface.
12 Issues can be different kinds of things we want to keep track of
13 but that do not belong into the source tree itself. This includes
14 bug reports, feature requests and license violations. We
15 might add more items to this list in the future, so feel free to
16 propose a new `type of issue' on the ffmpeg-devel mailing list if
17 you feel it is worth tracking.
19 It is possible to subscribe to individual issues by adding yourself to the
20 Cc list or to subscribe to the ffmpeg-trac mailing list which receives
21 a mail for every change to every issue.
22 (the above does all work already after light testing)
24 The subscription URL for the ffmpeg-trac list is:
25 http(s)://lists.ffmpeg.org/mailman/listinfo/ffmpeg-trac
26 The URL of the webinterface of the tracker is:
27 http(s)://trac.ffmpeg.org
32 Artwork such as photos, music, banners, and logos.
35 An error, flaw, mistake, failure, or fault in FFmpeg or libav* that
36 prevents it from behaving as intended.
38 feature request / enhancement
39 Request of support for encoding or decoding of a new codec, container
41 Request of support for more, less or plain different output or behavior
42 where the current implementation cannot be considered wrong.
45 ticket to keep track of (L)GPL violations of ffmpeg by others
48 Developer requests for hardware, software, specifications, money,
54 Bugs about data loss and security issues.
55 No feature request can be critical.
58 Bugs which make FFmpeg unusable for a significant number of users.
59 Examples here might be completely broken MPEG-4 decoding or a build issue
61 While broken 4xm decoding or a broken OS/2 build would not be important,
62 the separation to normal is somewhat fuzzy.
63 For feature requests this priority would be used for things many people
65 Regressions also should be marked as important, regressions are bugs that
66 don't exist in a past revision or another branch.
72 Bugs about things like spelling errors, "mp2" instead of
73 "mp3" being shown and such.
74 Feature requests about things few people want or which do not make a big
78 Something that is desirable to have but that there is no urgency at
79 all to implement, e.g. something completely cosmetic like a website
80 restyle or a personalized doxy template or the FFmpeg logo.
81 This priority is not valid for bugs.
98 Bugs which have been analyzed and where it is understood what causes them
99 and which exact chain of events triggers them. This analysis should be
100 available as a message in the bug report.
101 Note, do not change the status to analyzed without also providing a clear
102 and understandable analysis.
103 This state implicates that the bug either has been reproduced or that
104 reproduction is not needed as the bug is already understood.
110 Initial state of new bugs and feature requests submitted by
114 Issues which have been briefly looked at and which did not look outright
116 This implicates that no real more detailed state applies yet. Conversely,
117 the more detailed states below implicate that the issue has been briefly
121 Bugs or feature requests which are duplicates.
122 Note, if you mark something as duplicate, do not forget setting the
123 superseder so bug reports are properly linked.
126 Bugs caused by user errors, random ineligible or otherwise nonsense stuff.
128 */closed/needs_more_info
129 Issues for which some information has been requested by the developers,
130 but which has not been provided by anyone within reasonable time.
134 Bugs which have to the best of our knowledge been fixed.
137 Bugs which we will not fix. Possible reasons include legality, high
138 complexity for the sake of supporting obscure corner cases, speed loss
139 for similarly esoteric purposes, et cetera.
140 This also means that we would reject a patch.
141 If we are just too lazy to fix a bug then the correct state is open
142 and unassigned. Closed means that the case is closed which is not
143 the case if we are just waiting for a patch.
145 bug/closed/works_for_me
146 Bugs for which sufficient information was provided to reproduce but
147 reproduction failed - that is the code seems to work correctly to the
148 best of our knowledge.
150 feature_request/closed/fixed
151 Feature requests which have been implemented.
153 feature_request/closed/wontfix
154 Feature requests which will not be implemented. The reasons here could
155 be legal, philosophical or others.
157 Note2, if you provide the requested info do not forget to remove the
158 needs_more_info resolution.
