pb with mencoder transcoding engine on ubuntu 16.04

[fred987]

Hi,

Firstly, i would like to thank the developers 's team and all the contributors for their work with this amazing program.

Secondly, the problem i encoutered concerns the mencoder trancoding engine (Os: ubuntu 16.04).
I specified the executable path of mencoder program and the transcoding engine is marked as activated.

When i lauch the trancoding process on my tv, the program exit with a error message.

Here is an extract of the debug log:

I don't know if the problem is caused by my version of mencoder (1.2.1) or by a problem of misconfiguration.

I 'd really appreciate any help to solve this issue and i join the debug log for more info.

The problem is in MEncoderVideo (line 1384). For quick fix, you can replace the line

Code: Select all

encodeSettings += ":preset=superfast,crf=" + x264CRF + ",g=250,i_qfactor=0.71,level=3.1,weightp=0,8x8dct=0,aq-strength=0,me_range=16";

with

Code: Select all

encodeSettings += ",preset=superfast,crf=" + x264CRF + ",g=250,i_qfactor=0.71,level=3.1,weightp=0,8x8dct=0,aq-strength=0,me_range=16";

atamariya is right, and it will be fixed in the next version the fix is already in GitHub so feel free to build that, or if you want I can build it for you, let me know
