Samsung B transcoding 0.5 problem

Hi - first thx for all the effort you have put in for 0.5 - it's clearly got some nice improvements.

I was previously using 0.42, and had a transcoding profile set up to handle some picky .mp4 files i have that wouldn't play natively on my Samsung b-series screen. The transcoding worked fine, and was configured by changing the basic profile to the following:

<Video targetContainer="mpegts" targetACodec="ac3">
<Matches container="mp4" vCodec="h264" />
</Video>

(i.e. make all mp4 with h264 get audio transcoded to ac3)

Following the upgrade to 0.5, I made the same change, but the transcoding doesn't seem to work any more. I've browsed the forums, and seen that sometimes this is caused by the library not being complete. As such I reduced my library to one file, and confirmed that it was finished in both the GUI and the process manager. However, still no transcoding.

Looking in the log file I see:
2011-01-30 15:48:19,453 WARN [ProcessExecutor] Process C:\Program Files\Serviio\bin\\..\lib/ffmpeg.exe has a return code of 1! This is a possible error.

I have tried using different versions of FFmpeg, but they do not work.

When I roll back to 4.2 it works.

Is there anything you could recommend to fix this?

Many thanks

Hey Ray,

Maybe a long shot but I had some issues with sound in 0.5. Did you try forcing transcoding to "Downmix to Stereo"?

Cheers,
Zek

Hey Zek, thx for the suggestion.

Just tried - but unfortunately no luck. Also tried changing number of CPU's, and turning transcoding on and off to make sure it was set correctly. However, these didn't fix the issue either.

Any other ideas?

Cheers, Ray.

enable detailed logging, and try running the ffmpeg command it uses manually. post here the results

This is a bug (https://bitbucket.org/xnejp03/serviio/i ... nt-support). You can get around it by adding aBitrate="192" to the transcoding configuration elements.

Thx Zip - this has solved the problem. Really appreciate the help.

Can i play with my tv over DLNA or i always convert it on computer before play on tv?

thx

[zip]

Could be that the H264 profile is too high for the TV to play. Otherwise MKV is supported.
