Hi,

I am developing my own project of a humble multimedia player named JosePlayer. It is available as open source software from sourceforge. Yesterday I noticed that with version K-Lite_Codec_Pack_1756_Mega some files created with ffmpeg fail to render and directhow error says that source filter can no be loaded.

All files created with ffmpeg with the command line:

ffmpeg.exe -i %1 -acodec libmp3lame -vcodec libxvid -b:v 1200k -r 25 -s 640x360 -aspect 16:9 -ar 44100 -ab 128k -ac 2 %1.avi

fails to render.

With your media player those files are rendered, but I have tested those files with another independent player (TinyPlayer), also from sourceforge and it generated the same error than my media player.

I believe that may be some codec need some fix.

Thanks in advance and congratulations for your great work.

Does it also fail with the GraphStudioNext tool from the pack? That is good tool to test behavior of basic DirectShow players.

Inside GraphStudioNext if I drop that file it does not build the graph. There is only the file source filter. It hapens on 32 and 64 bits versions.

With an mp4 file created with ffmpeg my player plays the file and GraphStudioNext builds the complete graph.

Thanks for your attention.

Can you upload the failing file for me? Or at least a piece of it.

Hello again,

This link points to a short video of 11 seconds that shows this problem:

I do not work with a computer. I can only stay with my PC 3 hours at night and I just sit in front of it now.

This will solve it:
Codec Tweak Tool > Filter Management > DirectShow > disable "Bass Audio Source"

A bug in that filter causes the problem. It will get fixed soon. It is only include in MEGA pack, and you can uncheck it during installation.

You are right.

Disabling "Bass Audio Source" solves the problem.

Thanks you for your solution.
