maemo.org - Talk - MPV (mplayer fork) on Sailfish: no success :(

After some days dealing with this issue, lots of headaches, tricks, patches and the like, I have came to a dead end.

MPV compiles with success. But when it's time to open a video file, there's nothing. I have joined MPV official IRC channel and this is what they have told me:

Code:

mced

> Hi all, I'm trying to compile MPV for Wayland with no success. Stay here or join 

#mpv-player-dev?



l

> you can stay here



l

> also, obligatory worksforme™



mced

> ok, config.log says "Checking for Wayland... result is yes". But, at the ending, it says "Enabled optional drivers... video output: (blank)". Compling is successful, but "mpv -vo help" says nothing about Wayland.



w

> mced: do you have opengl headers?



mced

> I haven't checked that



mced

> I will see



l

> mced: moreover, you’re not using the waf build system, right?



l

> maybe the old one is broken



mced

> you're right, but I'm compiling version 0.1.7



l

> what. why.



w

> wow prehistoric



mced

> newer versions require Wayland not available on my platform



l

> fix your platform



w

> not sure why you want wayland



w

> and even less sure why an ancient version of wayland would be fine



l

> yeah, this



mced

> ok, it's a small phone called Jolla, which OS (Sailfish) uses only Wayland



l

> I see, but are they really using ancient wayland?



l

> that’s sad and surprising



mced

> let me check



y

> oh, you want to port mpv to jolla?



mced

> Installed    wayland-devel-1.1.0+git2-1.2.1.armv7hl



l

> y: not like much porting has to be done



y

> hehe



l

> sailfish is basically Mer with a custom UI



l

> or something



mced

> yep



y

> I know



l

> and Mer takes a bunch of things from opensuse



k

> how about hwacc?



y

> been following it almost since jolla became public



l

> k: difficult, thanks to SoC vendors being *******s



l

> qualcomm in this case, right?



w

> I doubt mpv would work on it anyway



mced

> yep, Qualcomm



w

> mpv doesn't support GLES for one



l

> w: *modern* mobile GPUs actually support regular opengl



w

> but apparently we (libass) can't get a new release done



l

> the problem is that the majority of devices still ship with 9 years old crap



w

> l: really?



l

> (hello powervr sgx530)



l

> w: well they kind of have to support something else for windows mobile stuff too :P



mced

> heh heh... I don't understand many of that, but thanks anyway



mced

> so it seems it won't work



l

> I’ll play around with it when I get my jolla device



l

> I still have that voucher for preordering, but I didn’t actually buy it yet



l

> bit of a financial problem right now, life sucks :V



y

> :(



mced

> that would be great, l. Blog, forum, any way of checking you?



l

> nope, I’m a web 1.0 person



mced

> hah hah



l

> mced: but to be honest, without hwaccel I don’t see mpv working well on that device



mced

> by hwaccel do you mean hardware decoding?



l

> and hwaccel probably requires openmax support, and will be quirky at best even when it works



l

> because qualcomm’s drivers are outright terrible



w

> yeah



mced

> it's a shame, because compiling MPV was being a lot of fun



mced

> lot of trouble



w

> well, if I ever get a not-dumbphone, I'll probably try to make mpv work on it no matter the costs



y

> nobody prevents you from trying mced



l

> Like LIMA, Freedreno is an open source driver for Adreno devices, in a mature enough state to run large applications like XBMC on top of an open source stack. Once again, Rob Clark from Freedreno did not get any help from Qualcomm: to provide a better driver for everyone, he had to reverse engineer the blob provided by Qualcomm and write his own shader compiler backend on top of the Mesa infrastructure. One person, working mostly alone, produced better quality drivers than a whole team working at Qualcomm. And because nobody seems to care about these issues, his work is not used by any major phone manufacturer or in any Android version that we know of.

mced

l

l

> well, assuming the jolla thing is adreno-based (I have no clue)



w

w

mced

> yep, Adreno 305



mced

> Qualcomm Snapdragon 400



l

> well, good luck with that then :D



mced

> thank you very much to all



l

y

... and then the conversation turned to Google Java Dalvik, systemd and closed SoCs.

What do you think? Keep trying to run "Mplayer" (actually MPV) is useless on Sailfish? Because I'm tired of things like unsupported XviD.

Repeating the steps I've followed:

1. Download MPV 0.1.7 source code, do ./configure --disable-x11 --disable-sdl --enable-wayland --disable-libass. It seems to detect Wayland...

Code:

============ Checking for Wayland ============



pkg-config --cflags wayland-client >= 1.0.0 wayland-egl >= 9.0.0 wayland-cursor >= 1.0.0 xkbcommon >= 0.3.0



pkg-config --libs wayland-client >= 1.0.0 wayland-egl >= 9.0.0 wayland-cursor >= 1.0.0 xkbcommon >= 0.3.0



cflags:

libs: -lwayland-egl -lwayland-client -lwayland-cursor -lxkbcommon



Result is: yes

... but there's no Wayland in the summary:

Code:

Enabled optional drivers:

    Input: pvr tv-v4l2 tv vcd dvb 

    Codecs: libavcodecs 

    Audio output: pulse oss 

    Video output:

After "make", checking video output:

Code:

./mpv -vo help

Available video outputs:

  null           : Null video output

  image          : Write video frames to image files

No Wayland and no output :(
