Does not compile against ffmpeg 7.x installed libraries

[dg362]

Many distributions have transitioned to the ffmpeg 7.x codebase.

dvbcut no longer compiles against these libraries as installed due to deprecated calls and API changes - at least that is what I believe off the back of errors.

There is a specific bug raised against Debian for this, and when compiling on either Trixie or Sid I get the same errors as this bug.

I have also tried on Arch with the same results.

Is there an intention to fix this such that dvbcut builds against ffmpeg 7.x libraries?
