Well read the title. How change the level in MPEG2 Elementary Stream. Mencoder can encode compliant MP@HL stream but the problem is that level flag is always Main Level even with 1080p encoding.

Yes, I had that same problem with Quenc.

I hacked a special version of DGPulldown to do it. Of course it doesn't belong in there, but it had all the MPEG parsing stuff, so...

If you want that, maybe I can find it again.

Yes ... :thanks:

If you know the particular sequencie code for MP@ML and MP@HL then I can use hexadecimal editor for replace the flag directly in the stream.

Try this little utility I made for you:

Let me know if there are any bugs. I tested it a little bit and it seems OK.

Work really well. I can make MPEG2 HDDVD compliant stream with mencoder now.
