Remux only option?

[Mattias]

Hello,

First of all, great piece of software. I've checking out a lot of DLNA servers and Mezzmo is doing a lot of things right.

Is it possible to specify a middle ground between on/off transcode such that the transcoding is limited to remux? I've encoded my DVDs with a lot of detail and cpu cycles into good h264 streams in mkv containers. I would love for the stream to not be transcoded unless needed.

My TV (Bravia NX) supports MPEG2/H264(AVC) video and AC3 audio. My MKVs all have at least an H264 stream and a AC3 stream (DTS too sometimes).

However my Bravia doesn't like MKVs and only allows MPEGTS containers. The process of just remuxing (not transcoding) the streams into a suitable container would take minimal work by Mezzmo and would guarantee that the stream retains my encoded quality.

is this possible? If not, could you consider adding that option under your transcoding checkbox?

Cheers,
Mattias

Hello Mattias,

Yes, Mezzmo actually supported remuxing, but we found that quite often it would crash FFmpeg, so we decided to adopt a safer approach of full transcoding for the time being. We're currently looking at ways of going around FFmpeg's bugs that cause the crashes, so hopefully soon remuxing will be back in Mezzmo (it's there internally, but is turned off at the moment).

Hi,

Apologies for replying to such an old thread, but this same issue came to light for me yesterday.
I have a Sony BDP-S590 and was trying to watch a 2GB AVI file that contained an Xvid video stream and AC3 audio.

Mezzmo needed to transcode the file for my player, but recoding the video to h264 took forever on my old PC. Well slower than realtime which meant I couldn't watch the movie without pre-transcoding.
However, we wanted to watch the movie there and then so it was a pain.

I did some research and used Avidemux to remux the Xvid & AC3 into an MKV container and now the Sony plays that fine without transcoding.

Interestingly though, I also tried with Serviio later on and my Sony BDP was able to play the original file fine without transcoding.
I'd like to understand why that was.

If you turn transcoding off, does the original AVI file play on your Sony BDP-S590? What device profile are you using with your Sony BDP-S590? Go to the Media Devices dialog in Mezzmo to see this.

Hi,

I am using the Sony BDP (PAL/NTSC, MKV, No Divx) Profile. I've confirmed this seems the best profile as it does MKVs and does not support Divx.
With Mezzmo transcoding switched off the Sony BDP-S590 plays about the first 10 seconds of the file and then stops playback and returns to the menu.

I've tried the same file from Serviio with transcoding also switched off and it plays fine on the player.

thanks for replying.

Thanks for the information, Richard.

We would like to see a set of logs when you stream the file with transcoding turned off in Mezzmo. Turn on logging (see http://forum.conceiva.com/showthread.php/419-FAQ-How-to-turn-on-diagnostic-logging) and restart your Mezzmo server. Stream the file and when it fails after 10 seconds, stop your Mezzmo server and exit Mezzmo. Zip up all the logs and send them to us at support [at] conceiva [dot] com.
