Change Fourcc

[Mounir]

I encode with mediacoder with x264 Cuda encoder, works fine on the pc. The problem is that the video is not read on my external device which is an LCD tv. It can read avc1 codec but not the type mediacoder produce which is "V_MPEG4/ISO/AVC" which is essentially the same thing i believe (correct me if i'm wrong)

I need a solution to not reencode so i thought of a fourcc changer but it seems hard to find.

Mux it using mkvmerge with --fourcc <FOURCC>, or mux it using mp4box with stype=4CC, or mux it using libav with -vtag fourcc switch.

Should i add this line (--fourcc <FOURCC>) in the Extra options > "user defined option" in mkvmerge gui (it return an error if i do that)?

Edit:
I can't find a stype option in mp4box gui

if you use mmg GUI then just fill in the new FOURCC string in the "FourCC" box of the "Format specific options" tab, after clicking on the video track.

If i enter 4CC in the fourcc box in MMG it return an error: "the Fourcc is not exactly 4 characters long"

I tried fourcc's: avc1 and H264 without result yet, not played on tv

If i enter 4CC in the fourcc box in MMG it return an error: "the Fourcc is not exactly 4 characters long" Huh? Put "avc1" in there.
