Entire response from AI:
1. [mmco: unref short failure] indicates that the H.264 decoder encountered invalid memory management operations in the stream.
2. [number of reference frames (0+5) exceeds max (4; probably corrupt input)] means the stream is referencing more frames than allowed by the profile, so FFmpeg discards one.
3. These warnings point to a corrupted or non‑standard H.264 stream, not an error in your command.
Summary: the second stream is problematic due to the combination of H.264 at 50 fps, AC3 audio, and a corrupted frame structure.
