Auto framerate/resolution plugin for WDLXTV

***** Download *************

Version 0.40 - http://www.mediafire.com/download.php?wudgjgzyn2y
Version 0.41 - http://www.mediafire.com/?2gn2nmjouoh
Version 0.42 - http://www.mediafire.com/?azzdzj2lm5j

Version 0.52 - http://www.mediafire.com/?c0et1nsidogbn43
Version 0.53 - http://www.mediafire.com/?rmcsfc5f4jzpnfc

***** Features *************

• on-the-fly selection of the best fitting resolution and/or framerate when playing videos,
  based on a video analysis with ffmpeg (works with hdmi connections only)
  
• preselection of an audio track based on the track's codec (and/or language for mkv/m2ts files)
  
• preselection of an subtitle track based on the tracks' language and/or mode (full/forced) for mkv files
  
• on-the-fly selection of an audio output mode (stereo/digital) based on the audio track's codec
  
• includes b-rad's autozoom plugin to help people with overscan issues
  
• the leds on the WD player can be disabled for video playback

***** Required firmware ******

WDLXTV-Plus - 1.03.29
WDLXTV-Live - 1.02.21
WDLXTV-G2 - 1.01.77

***** How to install *******

Put the files "autores.app.bin" AND "autores.conf" into your usb stick's root and turn on your WD TV with the usb stick plugged in. The plugin will load automatically.

***** Attention *******

This package is integrated into 1.02.21 based WDLXTV-Live & 1.01.77 based WDLXTV-G2 - you do NOT need this app.bin

***** Configuration ********

Edit the autores.conf on the usb stick.
All options in the config file are commented, read carefully!

********* Notes *************

If multiple output modes are available the script uses ffmpeg to choose the best setting.
Selection priority is in the following order:

1. Framerate
2. Resolution

********* Changelog *************

Version 0.53
- fixed a bug which prevented displaying the correct name and language of subtitles and audio tracks
- automatic audio/subtitle selection are disabled by default, edit autores.conf to enable
- updated autores.conf to version 7, older configs are not valid anymore

Version 0.52
- added support for WDLXTV-Plus 1.03.29
- added automatic audio track selection based on codec (and language for mkv/m2ts files)
- added automatic subtitle selection based on language and mode (forced/full) for mkv files
- audio output mode selection can be disabled for particular audio modes
- all features except resolution/framerate selection are working with rgb output too
- video analysis will be canceled after 15 seconds to prevent OSD hanging
- included a custom ffmpeg binary to detect forced subtitles
- removed mediainfo binary and libs
- updated autores.conf to version 6, older configs are not valid anymore
- an autores.conf file with windows line breaks will be automatically converted to unix format,
e.g. if you use the filemanager in the webend

Version 0.50
- integrated b-rad's autozoom plugin
- you can remove the usb stick after booting
- the autores.conf file must be always on the usb stick now
- single quotes in filenames are allowed now
- plugin will always prefer progressive mode, interlaced mode has to be enforced with filepath filter
- suggested_video_mode variable in the video info file was incorrect sometimes
- logging errors to /tmp/autores.log

Version 0.42
- fixed a bug with filename handling (mostly occurs with some media servers)

Version 0.41
- now the plugin works with with the UMSP media server too (e.g. apple trailers)
- configuration can be done by placing autores.conf on usb stick
- fixed a problem with audio mode detection

Ah, the first public release ? Nice, congrats, I couldn't use the WDTV Live without your plugin anymore

[inspectah_deck]

nice work, but i have no idea how to properly edit the autores.conf.
would be great if you could comment a litte bit for the not so tech-savvy people on how to change the settings.
what do i have to change to always let the script choose the correct framerate, based on mediainfo/ffmpeg.
i have a 1080p panel with all the videomodes supported.

Code: Select all

#####################  start of config  ########################
#
#  Set the video output resolutions/framerates you want.
#
#  BE SURE TO SET ONLY OUTPUT MODES YOUR TV SUPPORTS, OTHERWISE WITH ENABLED FORCEHDMI OPTION YOU GET A BLACK SCREEN !!!
#
#  The format is:
#
#  video_modes="
#  <pathfilter1>:<resolution1>|<resolution2>|...
#  <pathfilter2>:<resolution1>|<resolution2>|...
#  ...
#  "
#  pathfilter is an egrep pattern. The first filter matching the video filepath wins the race. Do NOT use spaces anywhere!
#
#  Below is my setting as an example, it contains all valid video output modes too:
#  My video filenames contain the refresh rate already ([60], [50], [24], [23.976]) and I want 1080p output.
#  If the refresh rate is missing let the script choose the best resolution/framerate, based on mediainfo/ffmpeg.
#  Just remove the resolutions you do not want (or your tv doesn't support)
#
video_modes="
\[60\]:1080p60
\[50\]:1080p50
\[24\]:1080p24

#  Use the next setting to force an audio output mode for specific files.
#
#  The format is:
#
#  audio_modes="
#  <pathfilter1>:<audio_mode>
#  <pathfilter2>:<audio_mode>
#  ...
#  "
#
#  pathfilter is an egrep pattern. Valid audio modes are: digital, stereo
#  If no filter matches, the audio mode configured in the WD TV settings menu will be used.

#  Audio output mode configuration based on parsing of ffmpeg output (mediainfo currently not supported).
#  This is an option for advanced users! Change it only, if you know what you're doing!
#  Currently used to set audio output mode to stereo for aac multichannel.

#####################  end of config  ##########################

This is the line you will want to edit:

*:1080p60|1080p50|1080p24|1080p23|1080i60|1080i50|720p60|720p50|576p50|576i50|480p60|480i60

In this line simply remove the resolution/framerates your TV doesn't support. For example, let's say you have a US TV, then it will most likely (there are exceptions !) not support 50 hz. (Most european TV's support both the european 50 hz and the US 60 hz standard, not sure if that's an indication of arrogance of one of those continents ? )

Also let's say your TV supports both 24h and 23.976 hz but only for 1080p (like my XBR9 does). In that case you'll end up with something like:

*:1080p60|1080p24|1080p23|1080i60|720p60|480p60|480i60

[thespecialist]

And to explain this part:

\[60\]:1080p60
\[50\]:1080p50
\[24\]:1080p24
\[23.976\]:1080p23

I'm not using this functionality myself, but here is what it does: you can bypass the whole 'video detection' phase, by adding something to your filename. For example, if you add [60] to your filename, then it will bypass detection and just use 1080p60 for that particular video file. If you remove that part from the config, then it won't do this. But if you don't plan on using it (like me), then you don't need to change anything here.

So for most users, all you need to do is edit that line that I explained in my previous post.

[inspectah_deck]

thanks for the quick reply.
i edited the line, but it´s kind of strange, my wd doesnt change the framerate according to the videofile.
i have the app.bin in the root of the usbdrive with all my movies in it.
the resolution is set to hdmi(auto) in the settings menu (which is 1080p60hz), but it doesn't change when i select a 23,976 fps movie for example. it always stays at 60hz.

The easy way to see if the plugin is even active is to watch the LEDS: by default the plugin switches off the LED's during video play. If that doesn't happen, the plugin hasn't been loaded/doesn't work.

Apart from that, I'm not sure how you concluded that the plugin doesn't work, it SEEMS you came to that conclusion by watching the menu but the menu itself never changes: the plugin just auto switches when you start playing a video and switches it back when you stop the video. Maybe your TV shows the used resolution/frequency on screen (mine does by switching it on/off), that's also an easy way of verifying that it works.

awsome thanks, now if I can get my daughter off the tv, I'll try it out

if you have access to your wd via telnet/ssh:
1) check contents of file /tmp/autores.log, it should contain something like "patching... all done".
2) during video playback do "cat /tmp/autores.tmp" on console. the file should contain infos about the video and the used resolution.

thx specialist for explaining some things

my samsung has an info button on the remote, where i can always see the current resolution/refreshrate, so it was during movie playback.
seems like the plugin isn´t working for me, the leds don´t turn off during playback.

if you have access to your wd via telnet/ssh:
1) check contents of file /tmp/autores.log, it should contain something like "patching... all done".

i think this looks fine:

Code: Select all

# cat autores.log
Waiting for dmaosd ...
Found dmaosd process (1633) ...
Found dmaosd version "WD TV Live 1.02.21", patching ...
All done!


2) during video playback do "cat /tmp/autores.tmp" on console. the file should contain infos about the video and the used resolution.

autores.tmp is not there, but i have an autores.sh.
this is what it shows during playback of a 23,976fps 1080p mkv, looks like alot of errors:

Code: Select all

# cat autores.sh
#!/bin/sh
