  3. PulseAudio update (5 min -- asked by remote) (flypig, 07:07:35)
    1. <remote> I'd like to inquire into PulseAudio version bump. (flypig, 07:07:42)
    2. <remote> Version 15 brings high quality codecs support for BT headphones. (flypig, 07:07:47)
    3. <remote> Is it planned? (flypig, 07:07:51)
    4. <Jolla> For general information, the PulseAudio repo can be found here: (flypig, 07:08:12)
    5. https://github.com/sailfishos/pulseaudio/ (flypig, 07:08:18)
    6. <Jolla> As can be seen there, we're currently on version 14.2, updated with the following commit. (flypig, 07:08:24)
    7. https://github.com/sailfishos/pulseaudio/commit/e0a3accd8840ecc728c32c1607c2950be5329eb8 (flypig, 07:08:31)
    8. <Jolla> Although it's no guarantee of future timescales, historically we've updated to even versions, with a roughly 18 month cadence between updates. (flypig, 07:08:36)
    9. <Jolla> Theres no update planned per se now. It's highly likely that this will happen at some point. (flypig, 07:08:44)
    10. <Jolla> Unfortunately our Audio expert is on summer holiday, thus we could not get his opinion for the PulseAudio update. (flypig, 07:08:51)
    11. <Jolla> We therefore propose that we come back to this topic during the next meeting in two weeks' time. (flypig, 07:08:57)
    12. <rainemak>: We did discuss switching to pipewire last year but that's much bigger effort (flypig, 07:11:31)
    13. Both PulseAudio 15 and Pipewire would help with Bluetooth audio codec support. (flypig, 07:13:39)
    14. https://forum.sailfishos.org/t/pipewire-replacing-pulseaudio/6196 (flypig, 07:24:23)

  4. RGB channel swapping in Canvas, Label, etc. (10 -- asked by poetaster) (flypig, 07:24:28)
    1. <poetaster> drawImage of Canvas renders images channel swapped. (flypig, 07:24:40)
    2. <poetaster> To expand see the Stopmotion code which applies the same fixes I applied to "Paint". (flypig, 07:24:48)
    3. <poetaster> Beside the RBG<->GBR swapping it also fixes the issue that image meta data (orientation for Portrait photos) is not being used when loading a url directly to Canvas. (flypig, 07:25:00)
    4. https://github.com/poetaster/harbour-stopmotion/blob/ee5ab00ab4328151ba0d9d78f7bca192c493a15a/src/ImageProvider.h#L95 (flypig, 07:25:11)

    6. https://forum.sailfishos.org/t/canvas-requestpaint-renders-image-data-tinted-blue/11349 (flypig, 07:25:29)
    7. https://forum.sailfishos.org/t/qml-label-dispays-images-with-a-blue-ish-tint/8818 (flypig, 07:25:34)
    8. <Jolla> Thank you poetaster for raising this, and also to gabrielg, Edz, attah and others in the forum for all your excellent detective work. This made understanding the problem a lot easier. (flypig, 07:26:03)
    9. <Jolla> We explored this a bit more internally and think we've got a solution. The qtscenegraph-adaptation package is used to store large images in hardware textures to speed up rendering. (flypig, 07:26:11)
    10. <Jolla> On hybris devices, when such an image needs to be accessed by the CPU it's done via the HybrisTextureFactory::image() function, in which eglHybrisLockNativeBuffer locks the buffer and provides a pointer to data in the buffer's native format. (flypig, 07:26:26)
    11. <Jolla> This can be either hybris's BGRA_8888 or RGBA_8888 and in this case it's hybris's RGBA_8888 format. Then the buffer is copied into a QImage(). (flypig, 07:26:34)
    12. <Jolla> But when we copy the data out we only specify Qt formats which are equivalent to hybris's BGRA_8888 order, consequently RGBA_8888 images come out with their colours swapped. The following change should fix it: (flypig, 07:26:40)
    13. https://github.com/sailfishos/qtscenegraph-adaptation/pull/2 (flypig, 07:26:53)
    14. <Jolla> However, we've not had a chance to test this across devices or use cases. (flypig, 07:26:58)
    15. <Jolla> Before merging the change, it would be especially helpful if members of the community could test the change with various apps on different devices. (flypig, 07:27:03)
    16. <Jolla> Testing it requires building and deploying the fixed branch of the qtscenegraph-adaptation package. Building can be performed using the application SDK. (flypig, 07:27:08)
    17. poetaster expressed his appreciation :) (flypig, 07:37:00)

  5. Community Bug Coordination Team summary (5 min -- asked by pherjung) (flypig, 07:38:03)

    2. https://forum.sailfishos.org/t/community-meeting-on-irc-7th-july-2022/12069/2 (flypig, 07:38:12)
    3. <Jolla> The Community Bug Coordination Team have done a superb job once again this fortnight. (flypig, 07:38:33)
    4. <Jolla> As a result of their work, we now have: (flypig, 07:38:40)
    5. <Jolla> - 10 new high quality bug reports recorded internally and tagged as "tracked". (flypig, 07:38:44)
    6. <Jolla> - 5 topics moved into different categories as they weren't really bugs. (flypig, 07:38:49)
    7. <Jolla> - 4 bug reports marked as "pending" more info. (flypig, 07:38:52)
    8. <Jolla> - 2 bug reports tagged as "fixed". (flypig, 07:38:55)
    9. <Jolla> - 2 bug reports related to RBG-BBR swapping which hopefully we'll be able to mark as "fixed" soon. (flypig, 07:38:58)

  6. Open Pull Requests (5 min -- asked by rainemak) (flypig, 07:43:32)
    1. <flypig> During the last meeting we agreed to have a section on open Pull Requests, to help prioritise our work in reviewing them. What did we get? (flypig, 07:43:39)
    2. <Jolla> We didn't get any submitted before the meeting, but everyone is welcome to raise interesting PRs for us to consider now. (flypig, 07:43:46)

    6. https://github.com/sailfishos/sailfish-browser/pull/959 (flypig, 07:49:02)

    8. https://github.com/sailfishos/droidmedia/pull/92 (flypig, 07:49:29)
    9. <dcaliste> Just for records, one way to see all opened PR on SailfishOS is (flypig, 07:57:01)
    10. https://github.com/pulls?q=is%3Aopen+is%3Apr+org%3Asailfishos (flypig, 07:57:02)

  7. General discussion (20 min) (flypig, 07:57:38)
    1. <rainemak> I could try to give a look & comment to dcaliste's browser PRs during this week. (flypig, 08:03:31)
    2. all Sailfish OS PRs: click the "Pull requests" link at the header, enter "is:open is:pr org:sailfishos" to the search field, press enter (rainemak, 08:04:04)
    3. ExTechOp raised the issue of long-standing network issues with Android. (flypig, 08:05:29)
    4. https://forum.sailfishos.org/t/android-connectivity-issues-analysis/12091 (flypig, 08:05:33)
    5. <mal> a small comment about pulseaudio updating, it needs first moving to meson since autotools support was dropped in pulseaudio 15, this means changing the custom patches to work with meson, I have done that but no pull requests yet, might need some more testing first (flypig, 08:24:05)

  8. Next meeting time and date (5 min) (flypig, 08:27:24)
    1. Next meeting will be held on Thursday 21st July 2022 at 07:00am UTC: 2022-07-21T0700Z (flypig, 08:28:34)
    2. <poetaster> color fix works! (flypig, 08:28:58)
