Oops: "10 fields" was "8 fields".
ffmpeg related (I hope)...
The Problem.
Traditional notation (example: 2-3 pull-down telecine) denotes sets of 4
film frames & 10 fields thus:
...frames... fields.
[1][2][3][4] --> [1][2][2][3][4]
[1][2][3][4][4]

Better, including time sequence, would be:
- *tbn* = the time base in AVStream that has come from the container.
- *tbc* = the time base in AVCodecContext for the codec used for a
particular stream.
- *tbr* = *tbr* is guessed from the video stream and is the value users
want to see when they look for the video frame rate.
In this ffmpeg output listing:
Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, top first),
720x480 [SAR 32:27 DAR 16:9], Closed Captions, 29.97 fps, 29.97 tbr, 90k
tbn, 59.94 tbc
what does "tbr", "tbn", and "tbc" mean?
I've searched the documentation but have not found Joy.

Hi,
I have one question:
For rtmp+flv, what's the difference between onMetaData and onCuePoint?
Thanks!
Regards
Andrew
