Changeset 3972 for pjproject/trunk/pjmedia/src/pjmedia-codec/ffmpeg_codecs.c

Timestamp:

Message:

Misc (re #1446): Updated ffmpeg video codecs default params:

• decoder fps to be 1.5x faster than encoder's, to encounter accumulated frames in jbuf when decoder clock gets short pauses in video setup (e.g: renderer creation, format change)
• separate size & fps for H.264 and H.263

File:

• pjproject/trunk/pjmedia/src/pjmedia-codec/ffmpeg_codecs.c (modified) (4 diffs)
