Red button makes nothing.

On other videos works audio switch ok.

Heheheh
I remember my internal program tool that helps to build Meteorite program. I think i needed to work on Meteorite.It's not completed yet

You can see that all audio tracks are type "AC3" with "header removal" compression applied. So there is nothing a DTS module can do. Also "header removal" compression is not fixed for general cases (at the moment just DTS).

Hello,

the last version of Meteorite cannot correct this audio problem. If the audio compression is with "header removal", then is no sound on tv. Is there an option to convert the file (with another program) to have the sound on tv?

Thanks

Meteorite just fix "broken MKV files". Not for just stable MKVs. Your problem is MKV version of your file is bigger than this TV could support. Please remux that file with mkvmerge gui with out header compression option.

I've noticed the extension is logging for me into files /dtv/samygodca_inj.log and /dtv/samygodca.log and i think it could cause some lag due to the amount of data logged when play back mkv files (my samygodca_inj.log was 1.1MB). Maybe it could be a good idea to have a samygodca.ini file to enable/disable data logging, and eventually the path of log file. Could also be used to enable libdca or not.

Edit 1:
I tried last 2.0 version and no more logging into file samygodca_inj.log and output into console is back again. Did you play with output logging (rose patching) ? I was actually wondering how to force nothing to be logged into exlink console output.
Also i've tried audio switch and it's working well with DTS/DTS and as previously said, it seems to have problem with AC3/DTS mixed tracks. Also dts soundtracks with header removal is still not working well for my files, i have laggy sound most of the time except the first 5 s.

Edit2: I've tried the files with DTS header removal with another external HDD and it's working. Duno why but my other external 2.5" HDD seems to have issue with only some files. I suspect an issue with the external HDD Jmicron controller (USB to ATA/ATAPI Bridge). Maybe there could be some conflict with the samsung kernel and that's why i see very high CPU usage for some files (usb-storage very high cpu usage into TOP command).

Hello again,

according this text http://www.bunkus.org/videotools/mkvtoo ... ompression is the cause of the problem in player (TV), not in video file. It is possible to convert this video to remove "header removal" with http://www.matroska.org/downloads/mkclean.html tool (mkWDclean binary). Works.

Wrong is the TV player, not video

I think there is no "wrong" here. Header Compression is not available feature since this TV's has been build. So ffmpeg version on TV doesn't support it too. It's new tech to decrease file size.
It's like MKV version 1 vs. MKV Version 2. Our TV is compatible with just V1.
But I think there is workarounds for this on TV too. But the simplest work around is removing header compression by muxing with MKV Merge GUI...

I've discovered that the playback lagging problem with some files is coming from a very heavy fragmented NTFS file system. Like Erdem said in this post: http://forum.samygo.tv/viewtopic.php?f= ... nted#p8188 if you have movie with very high number of fragment the USB controller from the TV could not seek at sufficient speed due to restricted CPU possibility, hence a sound and picture lag at some sequence of the file playback. So beware of fragmentation, and keep your volume defragmented when using with TV.
