Fix build with FFMPEG 5

[Vascom]

This change allow to build with FFMPEG 5.0.

Have you not found that you need to also remove this line to allow compilation with current builds of ffmpeg?

[Vascom]

What line? I just made this change and compile megasync at rpmfusion with FFMPEG 5.

[ChrisLane]

The line was linked in my comment. https://github.com/meganz/sdk/blob/b7e9a4d32e2dbaffa8831cc7122afe22a30cdb0b/src/gfx/freeimage.cpp#L305

It causes this compile error: https://github.com/meganz/sdk/issues/2576

[Vascom]

May be it need for latest release. I used 3.9.6.b to build megasync 4.6.5.0.

[Vascom]

Agree. Need to remove this line. It was done in other place of my spec-file to build megasync.

Came across this using Bookworm debian which has ffmpeg 5.

commenting out referenced line and converting the the line 316

[code] AVCodec* decoder = avcodec_find_decoder(codecId); [/code]

to

[code] const AVCodec* decoder = avcodec_find_decoder(codecId); [/code]

also seemed to be required.

for it to get past this and move on to other work (not finished yet)
