h2. Discussion results
173 129 Denis 'GNUtoo' Carikli
174 158 Denis 'GNUtoo' Carikli
h3.  Do we care about supporting devices with non-removable batteries? 
175
176
Points that were mentioned or discussed:
177
* This impacts the design decisions as supporting new devices through upstream code takes longer than hacking together the vendor code not to require nonfree libraries.
178
179
* Because of that either users, repair shops or Replicant device vendors will need to have a viable way to change the non-removable battery.
180
181
* If this is not the case it would force the Replicant project to race to try to support a device while it's still being sold new. If not users buying devices would have a battery that doesn't last enough when bought second hand.
182
183
* It's too hard, even for vendors like Technoethical which have some expertise in that area to upgrade non-removable batteries when the case is sealed. Practically speaking that could be done but the end result would not be as good as the new device, like the sealing would not be as good, making users damage the phone as they would expect the sealing to work.
184
185 162 Denis 'GNUtoo' Carikli
Consensus in that meeting:
186
* The cost for Replicant would be too high, so participant thought that not caring about devices without non-removable batteries and prioritize to support devices in Replicant through upstream project was better
187 158 Denis 'GNUtoo' Carikli
188 160 Denis 'GNUtoo' Carikli
h3. Do we require free software bootloaders ?
189 158 Denis 'GNUtoo' Carikli
190
Points that were mentioned or discussed:
191
* The Pinephone should be released in the next months (3 months?) but it's not released yet.
192 1 Denis 'GNUtoo' Carikli
* Some other devices with free software bootloaders are not released yet either
193
* Some concerns were raised on the fact that the Librem5 bootloader might contain nonfree software, which Replicant doesn't want to redistribute. A link to "Purism's plans":https://puri.sm/posts/librem5-solving-the-first-fsf-ryf-hurdle/ was also mentioned. Paul also mentioned that it might be possible that replacing the nonfree part was doable and that it would solve the issue
194
195 162 Denis 'GNUtoo' Carikli
Consensus in that meeting:
196
* Too early to do that: Replicant 9 is not out yet and it will work on devices with nonfree bootloader at first, but the work could be reused later by devices with free software bootloaders
197 160 Denis 'GNUtoo' Carikli
198
h3. Do we require isolated modems ?
199
200
Points that were mentioned or discussed:
201
* On one hand it would make it easier for users to understand the freedom privacy and security they are getting with Replicant. The information is often distorted up to the point where some users think that Puri.sm laptops are running only free software (while in reality there are non-free software involved in the boot such as the FSP, and a minimal Management Engine firmware). 
202
* On the other hand some users might already have devices that were supported by Replicant before and that don't have an isolated modem. This would leave such users with old versions of Replicant.
203
204
Consensus in that meeting:
205
* The devices with non-isolated modems might not be easy to support in Replicant 9 anyway, so we could drop them
206
* This will need to be announced for the Replicant 9 release as this way the information would propagate more efficiently to people.
207 158 Denis 'GNUtoo' Carikli
208
h3. How to handle the various keys used to sign releases, and other related things and should the recovery check signatures 
209
210
Points that were mentioned or discussed:
211
* The installation instructions need to be as simple as possible => If users have to check the signatures only once it's better. So now users check the recovery only, which then checks the rest.
212 1 Denis 'GNUtoo' Carikli
* The people involved in local Replicant install parties (in Paris) will help local Replicant users to update the recovery
213 158 Denis 'GNUtoo' Carikli
* Technoethical previously stated that the users having bought devices already running Replicant through them are either able to install new recoveries or that they are able to help them do it 
214
215
Consensus in that meeting:
216
* Keys usage in the short term: Developers sign with their keys
217 1 Denis 'GNUtoo' Carikli
* Keys usage in the longer term (requires time to implement it): use a keyring with the public key of several Replicant developers, like it is done in Parabola with the parabola-keyring package 
218 158 Denis 'GNUtoo' Carikli
* Keep checking signatures by default in the recovery
219
220
h3. Improve information for current and potential Replicant users
221
222
Points that were mentioned or discussed:
223
* Fil Bergamo plans to work on an unified table that has various information on devices supported by Replicant:
224 1 Denis 'GNUtoo' Carikli
* He plans to add in information about what hardware feature are supported or not
225 158 Denis 'GNUtoo' Carikli
* He plan to add information about how likely are the devices to be supported in the next Replicant 6 and 9 releases
226
* A "device getting guide" was also mentioned, to help users find which supported devices are the best for them
227
228
h3. Improving the Replicant website
229
230 1 Denis 'GNUtoo' Carikli
Points that were mentioned or discussed:
231 161 Denis 'GNUtoo' Carikli
* It would be nice to make information for users more accessible on the main page (https://replicant.us)
232 1 Denis 'GNUtoo' Carikli
233 159 Denis 'GNUtoo' Carikli
Consensus in that meeting:
234
* Also enable translations in other languages than English in the wiki, but warn readers that the information might be outdated when it's translated.
235
236 1 Denis 'GNUtoo' Carikli
h3. Making it easier for anyone to contribute to Replicant
237
238 159 Denis 'GNUtoo' Carikli
Points that were mentioned or discussed:
239
* A question was raised about making a welcome page for new Replicant contributors. That page is supposed to already exist in the wiki => Find it and look at it.
240
241
Consensus in that meeting:
242
* Create working groups on various part of Replicant (such as the documentation, f-droid issues, etc) and split the Redmine instance in sub-project accordingly. It would also enable to have different settings for the subgroups.
243
* Modify the [[People]] page to enable any contributor or potential contributors to add themselves in that page with the topic they would want to work on and the skills they have. The Replicant front page (https://replicant.us) would be modified to make sure that this is visible to potential contributors.
244
* Add pointers to C courses and to where to get the skills required to contribute to the Replicant system source code.
245
* Try to find a way to make a *simple* presentation on Replicant, that would give a simple overview how how Replicant and the hardware works.

257
Points that were mentioned or discussed:
258
* One of the main issue was the fact that people might have legitimate interest in linking to post from XDA which would contain both very valuable technical information, while not respecting the FSDG guidelines at all and pushing users to run nonfree software.
259
* Legal issues were raised as well when linking to external material and such.
260
* Some examples were given on how to handle some common issues:

** Link to a book chapter advocating for DRM on the FSF website:

266
  This chapter tries to justify the usage of Digital Restrictions Management (DRM).

  DRM is totally unacceptable as it requires the users not to be in control of their
268 124 Denis 'GNUtoo' Carikli
  computers to effectively prevent them from exercising their legal rights (such as fair
269
  use, or being able to copy published works). That chapter clearly shows the link between
270
  preventing users from controlling their hardware and effective DRM.

People in this discussion realized that the forum is relatively small so it's doable to have it moderated.
303 158 Denis 'GNUtoo' Carikli
304 1 Denis 'GNUtoo' Carikli
Plan of action:
305 158 Denis 'GNUtoo' Carikli
* Describe what should is acceptable or not for the forums, wiki, etc
306
** "Please do not distribute, recommend, or support non-free software here"
307
** Also describe the above examples there if possible to help people linking to information in the right way.
308
* How to handle violations of the policy
309
** On case by case basis. Help educate people on the matter and how to deal with it, especially on how to link to external information. |

h3. Do we ship some external applications in Replicant
313
314
Points that were mentioned or discussed:
315
* Yes, but how does the selection process would look like?
316 152 Denis 'GNUtoo' Carikli
* Which browser we should add => One that works and that doesn't have freedom privacy or security issues 
317 158 Denis 'GNUtoo' Carikli
* Firefox Lite was mentioned but it was dismissed due to very concerning privacy issues with its privacy policy
318

h3. Using wayland for the graphic stack?

h3. AOSP vs LineageOS
326
327
Points that were mentioned or discussed:
328
* Using LineageOS repos makes less sense due to consensus about supporting devices with removable batteries.
329 111 Denis 'GNUtoo' Carikli
* AOSP has stable/tagged releases whereas LineageOS lacks that 
330 147 Denis 'GNUtoo' Carikli
* AOSP is also better documented
331 113 Denis 'GNUtoo' Carikli
Since:
332 117 Denis 'GNUtoo' Carikli
* LineageOS uses many repositories from AOSP already (Implicit at the time of the talk, not explicited)
333 1 Denis 'GNUtoo' Carikli
* we still want some of the features from LineageOS (like root)
334
We will need to look into more details which repositories to use from LineageOS and from AOSP 
335 158 Denis 'GNUtoo' Carikli
336 162 Denis 'GNUtoo' Carikli
Consensus in that meeting:
337
* Getting closer to AOSP

h2. Video encoding

341
h3. Sound
342
343
The microphone was mono, with only a channel from the left. So we need to create mono audio files from the videos.
344
345
To make the sound go in both channel, do the following in Audacity:
346
347
* Create a new project with File -> New
348
* Import the video file with File -> Open
349
* Click on the audio channel -> Split Stereo to Mono
350
* Delete the second channel
351
* File -> Export -> Export as WAV
352
353 114 Denis 'GNUtoo' Carikli
h3. Video 
354
355
The videos were recorded with some equipement that was lent to us:
356
* A camera that outputed mp4 files on an SD card
357
* One wireless microphone
358
359
=> Next time ask if they have a second microphone available for questions.
360
361
* The videos are splitted in several mp4 files
362 115 Denis 'GNUtoo' Carikli
* The part before the presentation has to be removed
363
364
Kdenlive is being used for that.
365
366
Using kdenlive with Nouveau (with default settings), xfce4 under Parabola manage to freeze the screen (there are some messages like "nouveau: kernel rejected pushbuf: Cannot allocate memory" that can be observed when launching kdenlive through SSH).
367
368 116 Denis 'GNUtoo' Carikli
To workaround that the following was used:
369
* gnome3 (probably under wayland)
370 1 Denis 'GNUtoo' Carikli
* pushbuffer enabled in the module parameters for nouveau
371
372
=> It's still slow while zomming in the timeline but it manage not to freeze the whole graphics stack.
373
374
To edit a video with kdenlive:
375
* create a project, and select the right resolution (720p 25fps here)
376
* Import the videos files to use with project->Add clip
377
* Also import the mono audio files that you just converted with audacious
378
* Import the clips from the Project bin into the timeline with drag and drop
379
* Right click on the imported click in the timeline and select Ungroup
380
* Right click on the audio below, and select remove
381
* Import the mono audio file from the Project bin in the timeline with drag and drop
382
383
Once that is done you can remove the part before the presentation this way:
384
* In the timeline you can zoom at the maximum level 
385
* Use the cisors to divide the zone in two, you only need to click once with the left click to separate two zones
386
* Select the arow again (on the left of the cisors) and right click on the zone to remove, and select remove
387
* Do that for both the video and the audio tracks, then move both to the left to remove the gap done by the removal if there is one.
