@matze1980 Now it worked. The program i was using to convert the songs was making the bitrate bigger, due to my lack of attention. I put on a second song but now it just keeps playing and doesn't change to the first song i put on, why does this happen?
@acris Yes I appreciate it is highlighted but it is an easy mistake to make and one that can have unexpected results. It turns out that for me that the last 4 files I'd added were the problem. I didn't even notice their sample rate. Easy mistake like I say but worth letting others know.
I am immensely grateful with you! I swear I made my research in the forum and I found many topics that talked about this, but none of them were conclusive (the ones I saw). I found one that I think was the one I needed but it was in french, I translated with google translator, but I wasn't much of a help.
I found difficult to find the main theme.xml (even with WinSCP) but I did it.
I am truly grateful, thanks! You all make a great job!
Ihad the same problem. As @LBR59 said, the video is located here:
If you are on Linux (but I can imagine ffmpeg tools are also available on windows), this simple command line will create "outputfile.mp4" with the sound lowered:
ffmpeg -i recalboxintro.mp4 -vcodec copy -strict -2 -af "volume=-15dB" outputfile.mp4
Hope it may help
