Subject: [PATCH] {telegram-desktop,kotatogram-desktop}.tg_owt: add patch for
 FFmpeg 7
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These are forks of WebRTC, so include the same upstream patch we use
for FFmpeg 7 support in Qt 5’s WebEngine.

I didn’t bother deduplicating it across these two copy‐pasted
expressions since the original authors didn’t either.
