OpenPLi 8.1 - Webif bug

28 April 2022 - 21:32



I updated my STB from 7.3 to 8.1 lately, and I just noticed that editing timers in Webif does not work anymore (see attachment).

First problem : the channel selection box is not pre-filled (see "Select an option" on the right picture). I have to select the channel manually in the drop box otherwise I get the red error message.
Second problem : even if I select the channel manually, the modifications are not taken into account. This mean I can't change end time, for example.

Recompressing recorded movies with ffmpeg

22 April 2022 - 14:12


Did anyone manage to successfully recompress a film including DVB subtitles ?

I own a VU+ DUO² with a DVB-T tuner and I'm willing to compress some of my recorded movies (french numeric TV) for archiving.

These movies are MPEGTS files with, typically, one video stream, 3 audio streams, and 2 subtitle streams (DVD subtitles for hearing impaired and DVB subtitles).

Let's say I want to compress and remux video stream + audio streams n°1 and n°0 + DVB subtitles.
I would use the following command line :

./ffmpeg -i input.ts -map 0:v:0 -map 0:a:1 -map 0:a:0 -map 0:s:1 -vcodec h264 -acodec aac -scodec copy out.ts

I can check with ffprobe that everything is correctly muxed :

./ffprobe out.ts

Input #0, mpegts, from '.\out.ts':
  Duration: 00:01:02.52, start: 1.400000, bitrate: 3173 kb/s
  Program 1
      service_name    : Service01
      service_provider: FFmpeg
  Stream #0:0[0x100]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(tv, bt709, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 25 fps, 25 tbr, 90k tbn
  Stream #0:1[0x101](qaa): Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 130 kb/s
  Stream #0:2[0x102](fra): Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 130 kb/s
  Stream #0:3[0x103](fra): Subtitle: dvb_subtitle ([6][0][0][0] / 0x0006)

And when I play the file on my PC with VLC, all streams are working fine, including subtitles  :thumbs-up: 

BUT when I play the file on my Duo², the subtitles don't work. I mean I can select them in the menu but they won't display :(


My system is OpenPLI 7.3 with default media player.
Does anyone understand why media player won't display DVB Subtitles while VLC does ?


Optional question : what is the name of the process in charge of playing videos in OpenPLI ?


Resume on playback working only for recorded movies.

17 August 2021 - 18:53


Each file recorded with my DUO² has it's own resume point stored somewhere (in the corresponding .cut file I guess ?).
But when it comes to external files (DVD rip,camcorder, smarphone...), it remembers only the resume point of the last file that has been played.

Didn't find anyone mentioning this, is it the normal behavior ? haven't find any option for this.
