1 FFmpeg's bug/patch/feature request tracker manual
2 =================================================
8 FFmpeg uses Roundup for tracking issues, new issues and changes to
9 existing issues can be done through a web interface and through email.
10 It is possible to subscribe to individual issues by adding yourself to the
11 nosy list or to subscribe to the ffmpeg-issues mailing list which receives
12 a mail for every change to every issue. Replies to such mails will also
13 be properly added to the respective issue.
14 (the above does all work already after light testing)
15 The subscription URL for the ffmpeg-issues list is:
16 http://live.polito/mailman/listinfo/ffmpeg-issues
17 The URL of the webinterface of the tracker is:
18 http(s)://roundup.mplayerhq/roundup/ffmpeg/
19 Note the URLs in this document are obfuscated, you must append the top level
20 domain of Hungary to the tracker, and of Italy to the mailing list.
24 There is a mailing list to which all new issues and changes to existing issues
25 are sent. You can subscribe through
26 http://live.polito/mailman/listinfo/ffmpeg-issues
27 Replies to messages there will have their text added to the specific issues.
28 Attachments will be added as if they had been uploaded via the web interface.
29 You can change the status, substatus, topic, ... by changing the subject in
31 Re: [issue94] register_avcodec and allcodecs.h [type=patch;status=open;substatus=approved]
32 Roundup will then change things as you requested and remove the [...] from
33 the subject before forwarding the mail to the mailing list.
36 NOTE: issue = (bug report || patch || feature request)
41 An error, flaw, mistake, failure, or fault in FFmpeg or libav* that
42 prevents it from behaving as intended.
45 Request of support for encoding or decoding of a new codec, container
47 Request of support for more, less or plain different output or behavior
48 where the current implementation cannot be considered wrong.
51 A patch as generated by diff which conforms to the patch submission and
58 Bugs and patches which deal with data loss and security issues.
59 No feature request can be critical.
62 Bugs which make FFmpeg unusable for a significant number of users, and
64 Examples here might be completely broken MPEG-4 decoding or a build issue
66 While broken 4xm decoding or a broken OS/2 build would not be important,
67 the separation to normal is somewhat fuzzy.
68 For feature requests this priority would be used for things many people
75 Bugs and patches about things like spelling errors, "mp2" instead of
76 "mp3" being shown and such.
77 Feature requests about things few people want or which do not make a big
81 Something that is desirable to have but that there is no urgency at
82 all to implement, e.g. something completely cosmetic like a website
83 restyle or a personalized doxy template or the FFmpeg logo.
84 This priority is not valid for bugs.
99 Type/Status/Substatus:
102 Initial state of new bugs, patches and feature requests submitted by
106 Issues which have been briefly looked at and which did not look outright
108 This implicates that no real more detailed state applies yet. Conversely,
109 the more detailed states below implicate that the issue has been briefly
113 Bugs, patches or feature requests which are duplicates.
114 Note that patches dealing with the same thing in a different way are not
116 Note, if you mark something as duplicate, do not forget setting the
117 superseder so bug reports are properly linked.
120 Bugs caused by user errors, random ineligible or otherwise nonsense stuff.
122 */closed/needs_more_info
123 Issues for which some information has been requested by the developers,
124 but which has not been provided by anyone within reasonable time.
127 Bugs which have been reproduced.
130 Bugs which have been analyzed and where it is understood what causes them
131 and which exact chain of events triggers them. This analysis should be
132 available as a message in the bug report.
133 Note, do not change the status to analyzed without also providing a clear
134 and understandable analysis.
135 This state implicates that the bug either has been reproduced or that
136 reproduction is not needed as the bug is already understood.
138 bug/open/needs_more_info
139 Bug reports which are incomplete and or where more information is needed
140 from the submitter or another person who can provide it.
141 This state implicates that the bug has not been analyzed or reproduced.
142 Note, the idea behind needs_more_info is to offload work from the
143 developers to the users whenever possible.
146 Bugs which have to the best of our knowledge been fixed.
149 Bugs which we will not fix. Possible reasons include legality, high
150 complexity for the sake of supporting obscure corner cases, speed loss
151 for similarly esoteric purposes, et cetera.
152 This also means that we would reject a patch.
153 If we are just too lazy to fix a bug then the correct state is open
154 and unassigned. Closed means that the case is closed which is not
155 the case if we are just waiting for a patch.
157 bug/closed/works_for_me
158 Bugs for which sufficient information was provided to reproduce but
159 reproduction failed - that is the code seems to work correctly to the
160 best of our knowledge.
163 Patches which have been reviewed and approved by a developer.
164 Such patches can be applied anytime by any other developer after some
165 reasonable testing (compile + regression tests + does the patch do
166 what the author claimed).
168 patch/open/needs_changes
169 Patches which have been reviewed and need changes to be accepted.
172 Patches which have been applied.
174 patch/closed/rejected
175 Patches which have been rejected.
177 feature_request/open/needs_more_info
178 Feature requests where it is not clear what exactly is wanted
179 (these also could be closed as invalid ...).
181 feature_request/closed/implemented
182 Feature requests which have been implemented.
184 feature_request/closed/wont_implement
185 Feature requests which will not be implemented. The reasons here could
186 be legal, philosophical or others.
188 Note, please do not use type-status-substatus combinations other than the
189 above without asking on ffmpeg-dev first!
191 Note2, if you provide the requested info do not forget to remove the
192 needs_more_info substate.
