Sakari? I would want to discuss various v4l2_buffer improvements, e.g. - DMA-buf import with plane offsets, - unifying the buffer structs for M and non-M formats, - ability to import different FDs with offets for non-M formats if the layout matches driver expectations, etc. Besides that, I would be interested in the general idea on handling complex cameras in the Linux kernel in spite of the remaining V4L2 limitations, e.g. - combinatorial explosion of /dev/video nodes, - significant ioctl overhead, - huge amount of historical legacy making the driver and userspace implementations overly difficult and prone to repetitive mistakes, - the above also limiting the flexibility of the API - formats, frame rates, etc. set using distinct APIs, not covered by Request API, with non-failure "negotiation hell", etc. - lack of fences, etc. Best regards, Tomasz > > Thanks >j > > > If Collabora/Bootlin is there, I'd certainly want to discuss stateless > > codecs, in particular m2m codec helpers and finalize the specification > > in general. > > > > > > > > > > > On Mon, Aug 12, 2019 at 4:28 PM Hans Verkuil wrote: > > > > > On 8/12/19 6:00 AM, Alexandre Courbot wrote: > > > > > > On Thu, Aug 8, 2019 at 9:55 PM Mauro Carvalho Chehab wrote: > > > > > >> Em Thu, 1 Aug 2019 09:34:00 -0300 Mauro Carvalho Chehab escreveu: > > > > > >>> Em Sun, 30 Jun 2019 13:44:04 -0300 Mauro Carvalho Chehab escreveu: > > > > > >>> > > > > > Hi all, > > > > > > > > > > We are organizing a media mini-summit in Lisbon to happen in > > > > > September, > > > > > at the same week as the Linux Plumber Conference and the Kernel > > > > > Summit. > > > > > > > > > > We're still discussing the details about that. > > > > > >>> > > > > > >>> Gently reminder. > > > > > >>> > > > > > >>> Right now, we have just one extra theme proposal from Sean: > > > > > >>> > > > > > >>> - possible dvb improvements. > > > > > >>> > > > > > >>> If we don't have more proposals, we may end skipping the Media > > > > > >>> Summit this year. > > > > > >> > > > > > >> It sounds that we won't have material to have a media summit this > > > > > >> year. > > > > > >> So, let's cancel the media summit this year. > > > > > > > > > > > > Loosely related, but are there people planning to go to ELCE on > > > > > > 10/28-30?

Maybe we can come with a list of topics to discuss for all people present?

Re: [ANN] Media summit in Lisbon at September
That could be nice. Of course something more informal is also fine. Anyone else planning to attend? I suspect Laurent and people living in France might be there?

Loosely related, but are there people planning to go to ELCE on 10/28-30? Tomasz and I may attend if there is a chance to discuss libcamera/V4L2 codecs.

TBH, this wasn't much of a proposal. I wanted to have a little chat about a way forward to remove dvb_attach with the hardware I have, and some minor ideas about code improvement. This certainly can be done over irc, and I do not think it would be very interesting to the wider group. > If we don't have more proposals, we may end skipping the Media > Summit this year. I enjoyed meeting everyone in Edinburgh and I'd like to go to Lisbon, but if we don't have anything to discus then that's that, I guess. Sean

Nothing from my side. I wouldn't mind a brief chat with you about possible dvb improvements. I have started a few things already but it would be great to hear your ideas. Not sure this is interesting for the wider audience. Thanks Sean
