* avcodec/mpegvideo: Make new_picture an ordinary AVFrameAndreas Rheinhardt2022-04-01
| | | | | | | | | It is currently a "Picture", an mpegvideo-specific type that has a lot of baggage, all of which is unnecessary for new_picture, because only its embedded AVFrame is ever used. So just use an ordinary AVFrame. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/motion_est, mpegvideo: Make pointers to static storage constAndreas Rheinhardt2020-12-31
| | | | | | | | | Modifying static storage must not happen because of multithreading (except initialization of course), so add const to the pointed-to type for pointers that point to static storage.

* mpegvideo_enc: add intra_penalty option for p framesRamiro Polla2019-10-24
| | | | | | | | | | | | | | | This option allows more control over the use of intra macroblocks in predictive frames. By using '-intra_penalty max', intra macroblocks are never used in predictive frames. It is useful for glitch artists to generate input material. This option allows them to split and merge two video files while maintaining fluid motion from the second video without having intra macroblocks restoring chunks of the first video.
