[Libav-user] Huge packet sized during encoding

[Harald Schlangmann]

I just switched the encoder from H.264 to MPEG4 Part2(?) without changing anything else. 
The result is a file with a size of 394 MB instead of the 1.6 GB with H.264…
The “design size” at 2274 kb/s should be 61 MB plus audio…

Just in case this triggers an idea… It seems the bit rate defined in the codec ctx is not achieved in both cases, but the situation is worse for xlib264.

Is there probably something wrong with the frame rate? I write 30 frames / s, do I need to configure this somewhere? As written in my first mail, the timebase is set.

Greetings Harald
