| 5 | Not so obvious things
|
|---|
| 6 |
|
|---|
| 7 | There's still no manual or help in smplayer.
|
|---|
| 8 |
|
|---|
| 9 | So I think I should explain some things that are not so obvious.
|
|---|
| 10 |
|
|---|
| 11 | * Stop button. Pressing the Stop button once stops the video. If you
|
|---|
| 12 | press Play, the video will resume at the same point. But if you press
|
|---|
| 13 | Stop twice the time position is reset to 0, so Play will start the video
|
|---|
| 14 | from the beginning.
|
|---|
| 15 |
|
|---|
| 16 | * The pause button. The first time you click on it, the video is
|
|---|
| 17 | paused. The following times it will step to the next frame. This
|
|---|
| 18 | behavior only occurs with the pause button, not with the pause option in
|
|---|
| 19 | the menu.
|
|---|
| 20 |
|
|---|
| 21 | * Double clicking in the video window toggles fullscreen.
|
|---|
| 22 |
|
|---|
| 23 | * The Esc key can be used to exit from fullscreen mode.
|
|---|
| 24 |
|
|---|
| 25 | * The O key switches OSD modes (the same way mplayer does)
|
|---|
| 26 |
|
|---|
| 27 | * The option Open->URL doesn't check if you really typed a URL. What
|
|---|
| 28 | you type is passed to mplayer. So you may use this option to play not
|
|---|
| 29 | supported yet media, for instance TV channels, VCD, or anything
|
|---|
| 30 | supported by mplayer.
|
|---|
| 31 |
|
|---|
| 32 | * You can use the mouse wheel to go forward or backward.
|
|---|
| 33 |
|
|---|
| 34 | * Probably you'll have noticed that when you select some options the
|
|---|
| 35 | video window goes black for a moment and then resumes. This is because
|
|---|
| 36 | smplayer has to stop mplayer and start it again (with new options) and
|
|---|
| 37 | cannot be avoided.
|
|---|
| 38 |
|
|---|
| 39 | * If you play a DVD you'll see that smplayer won't save the settings
|
|---|
| 40 | (audio, subtitles and so on), so if you play it again later you will
|
|---|
| 41 | have to select your desired options again. Some time ago, smplayer did
|
|---|
| 42 | save the settings for DVDs but I removed it. Reasons: resuming playback
|
|---|
| 43 | at the same point is not possible (mplayer fault, it doesn't report the
|
|---|
| 44 | actual current time) and the disc had to be read twice, one for
|
|---|
| 45 | identifying it and other for starting playback. That could be very slow.
|
|---|
| 46 |
|
|---|
| 47 | * Deinterlace. mplayer has a lot of deinterlace filters. I have chosen 3
|
|---|
| 48 | for smplayer:
|
|---|
| 49 |
|
|---|
| 50 | * Lowpass5 (pp=l5). Works well most of the time, even with divx videos
|
|---|
| 51 | which have been bad deinterlaced. But this filter produces some "ghost"
|
|---|
| 52 | effect in movement scenes.
|
|---|
| 53 |
|
|---|
| 54 | * Yadif. It seems it works very well with mpeg files at full
|
|---|
| 55 | resolution. No ghosting, but some times the movement is not smooth. The
|
|---|
| 56 | bad part is that uses a lot of CPU.
|
|---|
| 57 |
|
|---|
| 58 | * Linear Blend (pp=lb). Produces a lot of ghosting and blurs the
|
|---|
| 59 | image.
|
|---|
| 60 |
|
|---|
| 61 | * Video filters:
|
|---|
| 62 |
|
|---|
| 63 | * Autodetect phase. Most movies and TV series (in PAL world) are not
|
|---|
| 64 | interlaced but progressive. But maybe in the computer they may seem
|
|---|
| 65 | interlaced (this happens to me sometimes with my dvd recorder). It
|
|---|
| 66 | seems that those videos have a field changed or shifted or something
|
|---|
| 67 | like that. "Autodetect phase" fixes it (-vf phase=A).
|
|---|
| 68 |
|
|---|
| 69 | * Denoise. This filter removes noise from the image, making it
|
|---|
| 70 | cleaner. But it could also remove a lot of details...
|
|---|
| 71 |
|
|---|
| 72 | * Deblock. If the blocks of a video are very noticeable this filter
|
|---|
| 73 | could help a little bit.
|
|---|
| 74 |
|
|---|
| 75 | * Dering. Actually I don't know what this filter does...
|
|---|
| 76 |
|
|---|
| 77 | * Add noise. Add a little bit of noise to the image. Can be useful to
|
|---|
| 78 | "cover" the blocks with noise or after a denoise, so the image doesn't
|
|---|
| 79 | look so extremely clean.
