DVBViewer Buffing on Kodi 17.5

e123enitan · October 18, 2017 at 5:32 PM

Appreciate any help or assistance

Recently I noticed when I lunch live TV (DVBViewer PVR) any HD channels will not load for a while, first it will display a black screen then follow with the live Tv display but will staggered a times, when I change channel to SD the response is quick to display, every other files types such HEVC, SD, HD plays well, just the the Live TV HD has an issue.

To understand why the HD channel behaves in the manner, I activate the debug to capture any issue or issues, to be honest i have no clue with code reading nor to understand the solution to this problem.

I am hoping YOU expert would be able to advice what could be done to alleviate the issue

Brief Errors

*MOD_EDIT*: we have the full log file for that.

What seem to stands out is the timing between the video/audio is out of sync

There is no issue in ffmpeg. ffmpeg is used for demuxing and audio playback. For video is used HW decoding (am_h264).

Code

22:33:21.558 T:545402122464   DEBUG: FactoryCodec - Video: am-h264 - Opened

There is probably issue in starting dequeue decoder buffer to output picture.

Try to upgrade to my test build, there is more descriptive debug log to help see decoder issue:

LibreELEC-S905.arm-8.2-devel-201710121457-gd562e8e-I.tar

BTW: From your log it is hard to classify playback as a ,smooth'. There is a lot of frame skips.

Create on SD new LE installation. Use this file:

LibreELEC-S905.arm-8.2-devel-201710121457-gd562e8e-I.img.g

Start LE from SD.

Have you replaced dbt.img with one corresponding to your box? In my SD .img is dtb for KI Pro.

Ok, let me give a try, my box is Tronsmart, I will check what you said, then see what results I obtain.

e123enitan · October 24, 2017 at 6:59 PM

Your Build

what do I change, coz I don't see diff, except more files in the first pic than your build

**afl1** · October 24, 2017 at 10:35 PM

You have to copy dtb.img from running SD card to new one. In your first picture 3rd file shown as 'dtb'.

e123enitan · October 25, 2017 at 2:34 PM

Got you thanks

I have good news, I was able to installed your build into and SD and it load LE nicely,

I have to confess with your mod, the issue is gone, change of channels is very fast, no more lag, quality picture is clear.

Still error with FFMPEG, as you said previously, this may not have anything to do with Live Tv streaming lagginess

Questions:

1, How do I get the remote to work, I used USB remote key to navigate

2, How do I write your mod into emmc internal, with my current mod it quite easy, once to click on the power there is option to write into emmc, so how does yours work.

Copy from your running version remote.conf to /storage/.config/

To find remote.conf submit via ssh command:

Code

find / -name "remote.conf"

For installing to internal flash memory use command:

Code

installtointernal

I see issue in missing fps info in video stream hints.

Code

00:23:28.689 T:3627021216   DEBUG: CAMLCodec::OpenDecoder hints.width(1920), hints.height(1080), hints.codec(28), hints.codec_tag(27)

00:23:28.689 T:3627021216   DEBUG: CAMLCodec::OpenDecoder hints.orientation(0), hints.forced_aspect(0), hints.extrasize(44)

AMLCodec uses fps for calculating decoder timesize window to deduce output readiness decoded frame. For 0 fps timesize is 0 and decoder looks like stalled. You can verify this by on-screen debug info pressing on keyboard CTRL-SHIFT-O. In debug info there will be 0 fps for video. I'll try to fix this issue in next test build.
