 Posted: Thu Mar 30, 2017 1:08 pm Post subject: [SOLVED] no audio on qupzilla (qtwebengine-5.7.1) |
 |
|
Hello, I'm trying to debug why qupzilla won't have play any audio (video seems fine).
I have installed
| Code: |
$ emerge -pv qupzilla qtwebengine ffmpeg
[ebuild R ] media-video/ffmpeg-3.2.4:0/55.57.57::gentoo USE="X alsa bzip2 encode gpl hardcoded-tables iconv libass mp3 network openssl opus postproc sdl theora threads vorbis webp x264 x265 xvid zlib (-altivec) -amr -amrenc (-armv5te) (-armv6) (-armv6t2) (-armvfp) -bluray -bs2b -cdio -celt -chromaprint -cpudetection -debug -doc -ebur128 -fdk -flite -fontconfig -frei0r -fribidi -gcrypt -gme -gmp -gnutls -gsm -iec61883 -ieee1394 -jack -jpeg2k -kvazaar -ladspa -libcaca -libilbc -librtmp -libsoxr -libv4l -lzma (-mipsdspr1) (-mipsdspr2) (-mipsfpu) (-mmal) -modplug (-neon) -nvenc -openal -opengl -openh264 -oss -pic -pulseaudio -rubberband -samba -schroedinger -snappy -speex -ssh -static-libs {-test} -truetype -twolame -v4l -vaapi -vdpau -vpx -wavpack -xcb -zimg -zvbi" CPU_FLAGS_X86="aes avx avx2 fma3 mmx mmxext sse sse2 sse3 sse4_1 sse4_2 ssse3 -3dnow -3dnowext -fma4 -xop" FFTOOLS="aviocat cws2fws ffescape ffeval ffhash fourcc2pixfmt graph2dot ismindex pktdumper qt-faststart sidxindex trasher" 0 KiB

And ffmpeg shows (I'm including some video codecs as well)
| Code: | $ffmpeg -codecs
...
DEA.L. aac AAC (Advanced Audio Coding) (decoders: aac aac_fixed )
DEA.L. mp3 MP3 (MPEG audio layer 3) (decoders: mp3 mp3float ) (encoders: libmp3lame )
DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (encoders: libx264 libx264rgb )
DEV.L. hevc H.265 / HEVC (High Efficiency Video Coding) (encoders: libx265 )
....
|
And I can play local files from all those formats. However, https://html5test.com/ reports that my browser does not support either of these codecs. Similarly youtube.com/html5 reports that my browser does not support h264.
qupzilla has ditched qtwebkit and therefore gstreamer since version 2, however just in case someone asks I have installed gstreamer with enough codecs to play aac mp3 without trouble on my box.

Just an idea, but have you tried installing the correct plugins for gstreamer, specifically?
The qtwebkit problem is at east according to the github page, an issue with that browser software...other browsers have built in rather than plugin that would bypass the need for other software, maybe there is an add-on or something that you could try that might allow better access for the html5 stream source  |

yes, as stated in my post. But anyway it is my understanding that this version of qupzilla does not rely in gstreamer.

This sentence I did not understand, but in any case it is my understanding that qupzilla ditched qtwebkit in favor of qtwebengine. |

My bad potuz. I think I clicked to post to soon. What i was suggesting is either the right setting or optional add-on that could get installed providing the easiest solution - like some browser addons for embedded video - bypassing the native video player. Is this an audio or video issue?
Are you sure that the streaming software on your local machine is not responsible for allowing access via something |

Personally, i would not be surprised if this was an issue actually with ffmpeg
I ditched it a long time ago, on both of my machines, although maybe it is back on one of them now due to dependency in one or another player or server/client setup can't recall.. |

Does it works in any other browser on your box?
I have many more ffmpeg flags.

Just my guess
| Code: | ASUS-G75VW roman # equery u qtwebkit
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for dev-qt/qtwebkit-5.7.1:
U I
- - debug : Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see
https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
- - geolocation : Enable physical position determination via dev-qt/qtpositioning
- - gstreamer : Enable HTML5 audio/video support via media-libs/gstreamer using SLOT 1.0
- - gstreamer010 : Enable HTML5 audio/video support via media-libs/gstreamer using SLOT 0.10
+ + jit : Enable just-in-time compilation for improved performance. May prevent use of some PaX memory protection features in Gentoo Hardened.
+ + multimedia : Enable HTML5 audio/video support via dev-qt/qtmultimedia
+ + opengl : Add support for OpenGL (3D graphics)
- - orientation : Enable device orientation detection via dev-qt/qtsensors
- - printsupport : Enable printing via dev-qt/qtprintsupport
- - qml : Build QML/QtQuick bindings
- - test : Workaround to pull in packages needed to run with FEATURES=test. Portage-2.1.2 handles this internally, so don't set it in make.conf/package.use
anymore
- - webchannel : Enable integration with dev-qt/qtwebchannel
+ + webp : Add support for WebP image format

qupzilla => qtwebkit => qtmultimedia
please check your use-flags for those qt-XY + kde related pacakges
qlist -Iv qt
qlist -Iv kde
to get a list of packages on your box
--
could also be the cause, not sure, just a thought, that this piece of software needs gstreamer?
https://discourse.trueos.org/t/qupzilla-no-sound-and-ssl-errors/363
have you tried another version of that software? |

I just found out about
| Code: | | portage/dev-qt/qtwebengine/files/qtwebengine-5.7.1-fix-audio-detection.patch |
So I'm recompiling against qtwebengine-5.7.1-r1, hope that's it.
Also I didn't want to recompile twice to check so I also added USE+="-bindist" because of this line in the ebuild:
| Code: | | $(usex bindist '' 'WEBENGINE_CONFIG+=use_proprietary_codecs') |
|

Marking this thread as solved, indeed it was an issue with qtwebengine. I do not know if it was forcing the WEBENGINE_CONFIG+=use_proprietary_codecs by using -bindist or if it was forcing the 'alsa' audio engine as per the patch. Anyway, this thread might be useful for someone with a similar setup. It's a pity that I had to recompile a few times qtwebengine (that takes over 2 hours in my laptop) to find this out.
To those with the similar problems. As I said in my first post, gstreamer, qtwebkit and qtmultimedia are completely irrelevant since qupzilla has ditched qtwebkit in favor of qtwebengine. Focus should be in the installation of ffmpeg (if using the external library USE in qtwebengine) and qtwebengine. |

Yes, version 1.8.9 of QupZilla is the last QtWebKit version, and it has been using QtWebEngine since 2.0.0 what comes to releases.
In 'dev-qt/qtwebengine-5.7.1' the audio detection changed (upstream) which indeed didn't quite seem to work for us, hence the patch (if there were issues with that, you could blame me for creating it, though I did not commit it).
The 'bindist' USE-flag is usually suggested to be disabled globally, /if/ the binaries created are not to be distributed, which is probably true for most personal use-cases. :]
As a sidey-note, 'ccache' can help when compiling the same thing again and again, though obviously too late to be of any good in this case...

Thanks, if it wasn't for your patch I wouldn't have solved this at all, I started looking at the ebuild only to see if they forced WEBENGINE_CONFIG+=use_proprietary_codecs and found the comment about the patch by chance.

I'm not sure why in the hell that USE flag entered my global make conf! I even thought it was part of the profile and was pissed off that I had to add -bindist in my package.use file for each QT package  I might be carrying that make.conf with that "bindist" for years without noticing.

Thanks I might try it again, I stopped using it when I started cross-compiling for a Raspberry-Pi and had hard to debug troubles that ended up being because of ccache. |

Glad it helped!

It is infact by default in the 'make.conf' that comes with the stage3, and if I don't remember horribly wrong, it is so that Gentoo can distribute them packages initially (or some of them).
From a quick look-see though, I can't seem to find mentions of it in the handbook other than this:

Yeah, I believe I've had to switch it off at times too, but not /too/ often. :]
