Files stopping mid playback

[crystalgipsy]

Hi I am having quite a few issues with streaming to my TV. From time to time the files just stop and it goes on to the next file in the folder.It seems quite random, If I then play the file again and FFW to just before the place it halted playback it will then play ok. I have a Samsung C650.

It seems to be a somewhat common problem. I've mentioned it to Dennis, as have a number of other members. Dennis mentioned that they're aware of one thing that may be causing this and are presently working to implement a fix.

Ok thanks hope they sort it soon.

Sry, i have to reactiveate this thread.

Since a few days, after the last Windows 10 Update my WD TV stops the playback sometimes in the middle of a movie. when i press start it starts from where it stops.

Its a WD TV Live hardware and the last 5.2 Mezzmo. Sometimes i saw problems in the displayed timeline ( i think on transcoded files only).

Not sure where the problem is, but perhaps someone has similar problems... I would help me to know where to sarch for errors :)

Thx, HTC

Does this problem occur only on transcoded files or on files that are pre-transcoded or playing without transcoding?

[HTC]

OK, after a long investigation time back again:

It happens when the files are transcoded to mpegts.

It does not depend from the used hardware, i tested WD TV, Sony TV, Sony BRP, Boxee and now the actual used PS4.

When i pretranscode the file to matroska and only change the Audiochannel everything works fine.

The Main Problem is that the timebar suddenly beginns to jump over the maximum length of the movie and therefore it stops, thinking the movie is finished... It looks like counting forward as expected and then suddenly a timejump of 10 to 20 minutes. I dont think it jumps everytime at the same timestamp... it seems to happen randomly.

The Problem beginns most after pressing ffw or rw, sometimes it stops also during normal playback.

Is there a posibility to create transcoding sheet for my ps4 with mkv as default/prefered transcoding format?

Also mezzmo often transcodes files that are playable without transcoding on the ps4. I turned transcoding complete off and found only one file with not supported audio format???

Can u please help me?

mkv files have an index at the end which is not available until the complete file is transcoded so for most devices this format does not work for transcoding on the fly. If you open the Sony Playstation 4 profile in a text editor you will be able to find the mkv section:

<avcontainer id="matroska" name="matroska,webm" mimetype="video/x-matroska" dlnaprofile="MATROSKA" encode="1" format="matroska" supportschunked="0" pretranscodeonly="1" level="41">
<video>
<format id="h264" encode="1" codec="libx264" ffmpegadditional="h264+encoding" preferredtranscoded="1">
</format>
<format id="mpeg4">
</format>
</video>
<audio>
<format id="mp3" encode="1" codec="libmp3lame">
</format>
<format id="ac3" encode="1" codec="ac3">
</format>
<format id="aac" encode="1" codec="aac" ffmpegadditional="aac+encoding">
</format>
</audio>
<ffmpegadditional id="union+thread0"/>
</avcontainer>

In the avcontainer there is an attribute pretranscodeonly="1". You can try setting this to 0 then save the profile and restart your Mezzmo media server to see if this allows files transcoded to mkv to play on the fly.

I will give your advise a try and give feedback if it works or not.

OK, seems like every file is working fine now.

A few ideas from my side:

When i start a file thet needs a pretranscode, the ps4 returned me to the file menu with the information "media is not playable" or something like that. It would sound better if i get a better information like "Media is transcoding now, please try again in XX:XX min".

A main question is also if i start a library maintainence, would mezzmo automaticly start the pretranscode of the files that need it?

Glad you are up and running now. The PS4's message that you see is their message (not Mezzmo's) so we cannot control that.

When you maintain your library, it will not pre-transcode your files. Maintain library is for finding & adding new files, collecting metadata for files, and removing non-existent files.

If you want to prepare files that have not yet been pretranscoded in your whole library or in a folder or in a playlist for your PS4, then you can use the Pre-transcode features. See this wiki topic how to pre-transcode only those files that require pre-transcoding for your selected device - http://www.mezzmo.com/wiki/doku.php?id=pre-transcoding_files.

OK, it wont work every time.

Your Transcoding is defective.

Seems like it happens only when the Files are transcoded to mpegts.

Fed up with the mezzmo, i will try another Media-server.
