LG - Fast Forward and Reverse

[avguru1]

Hello!

I haven't seen any recent thread on this and LG devices, so I thought I'd chime in.

I have play and pause and stop ability, but no rewind or fast forward.

Mezzmo 2.5.0, Windows 7 64.

MKV files played via a bluray player over a powerline AV network on a LG BD670 (Media Device is listed as LG Bluray (LPCM) ).

FWIW, the player plays out through an Onyko Reciever TX-SR508 via HDMI, and then to an LG 65LW6500 TV.

As a side note, I also notice occasionally when I hit STOP during movie playback, the movie stops, and the LG bluray player reports there was a problem with the server, and wants to return to the main menu. This isn't a big deal at all, stop is stop, but for bug testing, I thought I'd report it.

The rewind and fast forward, however, are an issue.

Thanks!

Well, I have an LG home theater and I always had problems with the MKV rewind or fast forward, with some MKVs it functioned but not with others until I read a post (I forget where, sorry) that said that you have to pass your MKV through MkvMerge (mkvtoolnix) and applied them the --clusters-in-meta-seek option (Muxing -> Add command line options - search in the available options combo the --clusters-in-meta-seek and click add).

I always do that with all my MKVs and verify also that the language in the sound tracks has been set, and I have no problems now with the fast forward or rewind.

I hope it helps.

That's interesting. Thanks!

I already use mkvmerge - Mezzmo cannot yet mute subtitles or switch audio tracks - to make the files appropriate for viewing.

I'd love to hear if the fast forward / rewind this is a known issue, and slated to be remedied.

Thanks again!

Does FF/REW work on native files and files that already have been transcoded (or pre-transcoded) or is it not working for even native files?

Good Question.

I added the TranscodingFiles (C:\Users\xxxxx\AppData\Local\Conceiva\Mezzmo\Tran scodingFiles) to Mezzmo and tried to play an MZT file from the video folder. The LG BD player did not recognize that the folder had any transcoded files in it (there was 1 file, 5.3 GB, which I can manually have VLC open on the host PC). Thus, I can't test....unless I am missing something.

Thanks!

You should not add files from the special transcoding folder (C:\Users\xxxxx\AppData\Local\Conceiva\Mezzmo\Tran scodingFiles). Mezzmo will not pick them up since they have a .MZT file extension and this is not a known media file extension. Rather, the Mezzmo application lets you control how you use and stream your transcoded files.

If you want to stream a transcoded file, then you need to do the following steps in Mezzmo:


Right-click on an original file in Mezzmo that you wish to steam and click Properties. This will display the 'Properties' dialog. Go to the Transcoding tab and see if there are any transcoded files for this original file. If there are, then you can select individual transcoded files and they will be set to 'Preferred'. When set to Preferred, this means that the selected transcoded file will be streamed to the device when you choose to play the original file on your device. This lets you test what transcoded files work and do not work.
If there are no transcoded files for an original file, then you can pre-transcode a file using the Pre-Transcode File dialog. Right-click on a original file in Mezzmo and click 'Pre-transcode File'. Then you need to select the device and format(s) you want to transcode to. All transcoding is displayed in the Transcoding pane in Mezzmo. After the file has completed transcoding, then the transcoded file will be set to Preferred and will be streamed to your device the next time you try to play the original file.

I'm confused, my LG home theater supports the MKV format, so there is no need for transcoding, I always passed the MKVs through MKVmerge and do the procedure mentioned some posts above and sometimes I add another sound track language (french for my son, we live in Quebec), and the LG allows me to navigate, and/or change sound tracks or subtitles by using the INFO/DISPLAY button on the remote which opens a small menu with the time tracking, audio tracks and subtitles tracks that I can change.

Is it not the same with the others LG devices ?

Paul:

The plot thickens:

In Mezzmo, I selected the file that I could not rewind / fast forward, selected pre-transcoded files, selected the appropriate device (along with the "only pre transcode files that have not been pre-transcoded yet". When I choose formats, I select mpegts with mpeg2video and ac3. Since this is HD content, I presume that is right. I do NOT select Force full transcode. I click OK, then YES, and I get a message saying that my files were not queued for transcoding since they match the formats that are supported. (I tried MPEG NTSC as well). This tells me that my system isn't transcoding because the fields in question play natively.

So, I guess I'm back at square one....the media appears to be native, and I still cannot rewind / fast forward. However, read my response to Ediaz below...

Ediaz: I never tried that - I always just tried to use the rewind and fast forward buttons , which gave me the red crossed out circle icon, indicating NO. I never attempted to go into any sub menus. Is that the expected behavior? Works when going into sub menus but not when using the fast forward & rewind buttons?

What BluRay player are you using, and what device name are you using? (LG BluRay LPCM?)

As always, thanks all.

[ediaz1963]

Well, if you can't navigate using the Fast Forward/Rewind buttons you won't navigate with INFO/DISPLAY menu either. As I said on my original response, to be able to navigate I have to add the --clusters-in-meta-seek command line option to the MKVmerge.

I have a LG HB405SU, bought in 2010 and using the LG BluRay LPCM profile.

Since the LG has MKV support I always thought that Mezzmo streams the file as is and the device will look at it and decide what it can do with it. So I always thought that there was some information missing IN some mkvs so the LG cannot navigate through them, belief that is supported by the fact that I found, thanks to others, the way to include the missing information IN the mkvs.

[avguru1]

Actually, I find that to not be the case.....

I attempted fast forwarding and rewinding via the INFO/DISPLAY menu (incrementing by minutes)...I can do that without any issue. Awesome! it's the fast forward and rewind dedicated buttons that do not seem to work. None of these files had the --clusters-in-meta-seek added when I used mkvmerge; I only stripped out other audio tracks and subtitles.

[ediaz1963]

Well, in that case and as you already have said... the plot thickens

I have never been able to navigate with the time tracker if I cannot do it with the FF/Rewind buttons.

And I have never had to strip tracks to do anything, on the contrary, I sometimes add tracks, which I switch with the INFO/DISPLAY button.

I still think that Mezzmo just streams the file and the LG devices detect what can they do with them or not, and I suspect that there are differences on the MKV format support between devices.

Anyway, I'm glad that you can now navigate on your movies !
