Issues with transcoding, unable to play media

Dev Community Apps & Creations

Hi all,

there a couple of days that I can’t run some films. The strange thing is that I can run them from another source like a Samsung SmartTV.
Each time I trying to play these films appear a message “Transcoding: Unknown video codec” after that another message “Unable to play media: please check that this file exists and the neccessary drive is mounted”

I have a Raspberry PI version B with 512Mb, a SDHC class 10 8Gb. The connection is Ethernet. The version of Rasplex is the latest 0.6.0. I have installed RasPlex by disk imager OSX.
I have followed instruction on GitHub but I can’t get log file, from SSH session is telling me that “rasplex” password is not correct for user “plexuser”
Version of Plex Server is 0.9.12.3.1173-937aac3
Type of plex server: NAS on Synology
Power supply: via usb cable from TV

Thanks all

Ok I’ve the log. Also the video that I try to play is an avi. The codec I think is MPEG2 and other information I don’t know how to “read” in the file.

I see from log file this two row:

00:05:02 T:1796207696 DEBUG: CPlexTranscoderClientRPi : Codec MPG2 was not found.
00:05:02 T:1796207696 DEBUG: CPlexTranscoderClientRPi : Codec WVC1 was not found.

What mean ? And why from Samsung SmartTV I haven’t this problem ?

I found also this article:
Buy MPEG-2 license It means that I need to buy the license ? Why one or 2 month ago I didn’t have this problem ? I played MPEG-2 file anyway.

Rasplex has never been able to play MPEG2 files without a licence from raspberrypi.org.

Maybe Samsung pay the licence fee for MPEG2, who knows, Smart TV - £1000 approx, Raspberry Pi - £30 approx!

lower you mpeg-2 streaming quality (force your plex server to transcode) that may work.

Ok. Now I purchased (for 5 euros) license for MPEG-2 and WVC1. Rasplex tell me that it find the codec, but the problem still remain. Can you help me ?

Here there is log: PasteBin

I did also that but still not working… :frowning:

If you’re still using RasPlex 0.6.0, then please try installing or updating to RasPlex 0.7.0 instead.
For a new install, make sure to download and use the new and improved RasPlex installer.
Hopefully the new release will eliminate the problems you had.

Did you enter the license details in config.txt?

I’ve updated to Rasplex 0.7.0 and yes I’ve entered license details in config.txt.

The problems still remain. It continue to say “unknown codec”.

I tried some tests. One with Force Transcoding Off and one with Force Transcoding On.

Each time I find this string inside log:
17:07:39 T:1969602560 INFO: CAESinkALSA - ALSA: /home/dale.hamel/workspace/rasplex/OpenELEC.tv/build.RasPlex-RPi.arm-devel/alsa-lib-1.0.29/src/confmisc.c:392:(snd_func_concat) error evaluating strings 17:07:39 T:1969602560 INFO: CAESinkALSA - ALSA: /home/dale.hamel/workspace/rasplex/OpenELEC.tv/build.RasPlex-RPi.arm-devel/alsa-lib-1.0.29/src/conf.c:4260:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory
No such file or directory, what mean ? Which file or directory ? I’m not an expert of OpenELEC.

Also I found this one:
17:17:11 T:1602864208 DEBUG: RPi ShouldTranscode decided to transcode, Reason : Unknown video codec : 17:17:11 T:1602864208 DEBUG: CPlexMediaDecisionJob::DoWork Item should be transcoded 17:17:11 T:1602864208 DEBUG: CPlexMediaDecisionJob::DoWork final URL from MDE is plexserver://20ceafd68989c4c5c0a4541c47f88be0cb0a2aef/video/:/transcode/universal/start.mkv?copyts=1&directPlay=0&directStream=1&maxVideoBitrate=20000&mediaIndex=0&path=%2flibrary%2fmetadata%2f9064&protocol=http&session=6c1b0c46-ea73-4b41-a8ec-34353a2df734&videoQuality=100&videoResolution=1920x1080
Why is talking about matroska ? the file has an AVI extension and not an MKV.`

Here the log with Transcoding Off: http://pastebin.com/psxh0Qbn

Here the log with Transcoding On: http://pastebin.com/6ECSZPMe

Also, for user NedtheNerd, I did the command line for verify the license of MPEG:

RasPlex:~ # vcgencmd codec_enabled MPG2 MPG2=enabled RasPlex:~ # vcgencmd codec_enabled WVC1 WVC1=enabled

12

Has anyone an idea how to solve ?

13

It’s being looked at.
