I already wrote about it. Together with independent ffmpeg libraries size is about 4Mb.

[christophecvr]

Wel ter info I'm just trying something now to have just the required wma codecs for decoding , and then only the pcm encoders. See what it will bring.

 

The gst-libav is 13.7 MB . Whithout any codec 889 KB but off course I need something.

[christophecvr]

I already could produce a working gst-libav on vuduo2 from 5,2 MB instead off the 13.7 by just adding to gstreamer1.0-libav_git.bb

LIBAV_INCLUDED_EXLUCED = "--disable-encoders --disable-decoders --enable-decoder=wmalossless --enable-decoder=wmapro --enable-decoder=wmav1 --enable-decoder=wmav2 --enable-decoder=wmavoice"

LIBAV_EXTRA_CONFIGURE_COMMON_ARG = "--target-os=linux \
  --cc='${CC}' --as='${CC}' --ld='${CC}' --nm='${NM}' --ar='${AR}' \
  ${GSTREAMER_1_0_DEBUG} \
  --disable-mipsdsp \
  --disable-mipsdspr2 \
  ${LIBAV_INCLUDED_EXLUCED} \
  --cross-prefix='${HOST_PREFIX}'"

Shure i should be able to decrease it more as there is more which can be removed. But that will be for tommorow

Till now as far I know gst-libav is only required for wma.

 

Now motogp free practice at austin.

If you remember, it is a question that I asked earlier.
What of the gstreamer plugins and codecs are used in the receiver?
I in addition I disable in ffmpeg codecs that dubble gstreamer plugins, but I am sure that the remaining all are not used.

[malakudi]

I built the ffmpeg recipe in master-next but it only builds ffprobe and ffserver (and libraries). It doesn't build ffmpeg binary. What needs to be changed to also build ffmpeg, anyone got a clue?

The plugins used currently on stb are all required. We well build more but that's ok.

 

As for gst-libav it is trough that normally only codecs are required for wma and that's it. (and the minimum required packages to run those codecs) The codecs are from ffmpeg .

 

I already to succeed to reduce the single .so file which gst-libav installs from 13.7 MB up to 1.2 MB.

[christophecvr]

Ok here the full gstreamer bundle again.

 

What is changed. The gst-libav will only have the wma-codecs. All the others are already on board or covered by gstreamer plugins.

 

What do You win instead off a libgstlibav.so file off 13.7 MB a libgstlibav.so file off 1.2MB considerable I guess.

 

What I did to the gst-libav recipe for that .

 

changed gstreamer1.0-libav_git.bb file to

LIBAV_INCLUDED_EXLUCED = "--disable-everything \
			--enable-decoder=wmalossless --enable-decoder=wmapro --enable-decoder=wmav1 --enable-decoder=wmav2 --enable-decoder=wmavoice"

LIBAV_EXTRA_CONFIGURE_COMMON_ARG = "--target-os=linux \
  --cc='${CC}' --as='${CC}' --ld='${CC}' --nm='${NM}' --ar='${AR}' \
  ${GSTREAMER_1_0_DEBUG} \
  --disable-mipsdsp \
  --disable-mipsdspr2 \
  ${LIBAV_INCLUDED_EXLUCED} \
  --cross-prefix='${HOST_PREFIX}'"

By me all ok no media breakdown and wmv/wma still works perfect on vuduo2

 

For others needs to be tested

 

note : I also add the gstreamer1.0-plugin-multibox-dvbmediasink.bb recipe.

ok, the AV sync issue is caused by something from the OE's gst recipes. With PLI's recipes it's OK (for these I use -disable-introspection)

[christophecvr]

With the above gsteamer-git-head-1.9.0.1 no sync issues att all. And introspection is used.

I used the same rev, 1.8.0 tagged in both cases... but now once I reconfigured the pli's libav recipe for ffmpeg, I'm seeing the issue there, too... strange

[Taapat]

What needs to be changed to also build ffmpeg, anyone got a clue?

 

Pay attention to the config options.
To build ffmpeg binary is needed to build all ffmpeg libraries the ones it uses.
If you disable any of them then ffmpeg binary is not builded.

[Taapat]

If from the libav used only wma codecs then I think that really is not worth using a newer version of ffmpeg from the system and can be used 3.0 version in libav.

 

P.S.

I see that on version 1.9.0.1 has returned problem with live hls streams. They are not running.

But that's another story. It seems to me that the 1.8.0 version is not so stable as expected.

By me it runs ok all hls streams.

 

Do not forget to install

 

gstreamer1.0-plugins-bad-hls  (is not in enigma2.bb recipe yet as this plugin is only there since 1.7.2 ) and the gstreamer1.0-plugins-bad-fragmented must be removed out off enigma2.bb for gst >= 1.7.2

[Beeker]

@Taapat

If you  building gstreamer-plugins-bad with bbappends

Please remove in gstreamer-plugins-bas_git.bb(OE-Core) the unnecassery,obsolete,depraceted,breaking only things,not working, lazy to apdapt other recipes... code:

PACKAGESPLITFUNCS_append = " handle_hls_rename "

python handle_hls_rename () {
    d.setVar('RPROVIDES_gstreamer1.0-plugins-bad-hls', 'gstreamer1.0-plugins-bad-fragmented')
    d.setVar('RREPLACES_gstreamer1.0-plugins-bad-hls', 'gstreamer1.0-plugins-bad-fragmented')
    d.setVar('RCONFLICTS_gstreamer1.0-plugins-bad-hls', 'gstreamer1.0-plugins-bad-fragmented')
}

You can try to keep -gstreamer-plugins-bad-fragments-  in enigma2.bb, but that was not working 100% either as i remember.   

For now it's better to use own gstreamer recipes(at least gstreamer-plugins-bad) like christophecvr and i do.
 

[Taapat]

@christophecvr do you really tried live hls streams?
For me, hls streams work, does not work live hls streams.

 

 

@Beeker why do you think that it's not necessary?
I am in my enigma a long time ago changed the dependence on gstreamer1.0-plugins-bad-hls: https://github.com/T...12bc420afddedbc
But I suppose there are some plugins, which can depending on the gstreamer1.0-plugins-bad-fragmented, so it is right that gstreamer1.0-plugins-bad-hls provides gstreamer1.0-plugins-bad-fragmented.

 

P.S.

I think that with this gstreamer issues we should move to gstreamer topoc .

[christophecvr]

@Taapat yes here two I tried.

 

The first was already ok with the old gst below <1.9

 

The second runs fine by me since 1.9 (p.. i did not test 1.8)

I think You're problem is the change over from

 

gstreamer1.0-plugins-bad-fragmented to gstreamer1.0-plugins-bad-hls  which is the cause why You have problems with hls streams on gst 1.8 or higher

I'm now just in the case study about wmv (video codecs)

 

At this time the codecs who run nice (on duo2) are :

0:00:00.242337963  5154 0x7558d030 INFO            dvbvideosink gstdvbvideosink.c:1409:gst_dvbvideosink_set_caps:<dvbvideosink0> caps = video/x-wmv, wmvversion=(int)3, format=(string)WMV3, width=(int)320, height=(int)240, codec_data=(buffer)4df90a01, framerate=(fraction)25/1, pixel-aspect-ratio=(fraction)1/1

The older wm1 does not run. I just adpat the wmv cap to have the video cap anyway first by modifieng gstvideosink.c wmv cap from :

#ifdef HAVE_WMV
	"video/x-wmv, "
		VIDEO_CAPS ", wmvversion = (int) 3; "
#endif

to :

#ifdef HAVE_WMV
	"video/x-wmv, "
		VIDEO_CAPS ", wmvversion = (int) [ 1, 3 ]; "
#endif

the video cap is then showing up. However does not play. (audio plays wma)

So it looks like indeed only modern wmvversions are running. The base VC1  (used for HD formats) the VC1_SM is normal (used for SD formats) .

 

Since wmv versions 3 are supported , all media made with mediaplayer 9 or above. I would be surprised that the older wmv1 dus not work with the wmv on board codecs. Ok it is possible but ...

 

I rather think it's a problem off type threatement into gstvideosink.c  which at base had a cap limited to 3 only , but I think changes could be possible based on the wmv1 fourcc value question is which ?
