Δουλευει out of the box με το cx8800 και το tvtime δειχνει κανονικα την εικονα απο composite (/dev/video0:input=1)

 

Οταν ομως να κανω record με:

η εικονα ειναι παραμορφωμενη :

Δεν εχω να προτεινω κατι, απλα δες αν μπορεις να ορισεις πως το σημα που ερχεται στον mencoder ειναι σε pal.

Η εικονα που καταγραφεται μου δινει την εντυπωση ειτε μισοκατεβασμενου αρχειου, ειτε κακη εγγραφη απο αρχειο προστατευμενο απο εγγραφη (σαν να συνδεεις 2 dvd recorder με scart και να πας να αντιγραψεις ενα προστατευμενο dvd).

[tritonas00]

με norm=pal παλι τα ιδια κανει.

 

μου κανει εντυπωση, γιατι το tvtime δειχνει σωστα την εικονα απο composite.

 

 

 

υπαρχει τροπος να δουμε σε commandline τα options που χρησιμοποιει το tvtime?

[jim_p]

Απο το man tvtime

-S, --saveoptions

Save command line options to the config file. This will save the V4L device, VBI device, input number, norm, frequency, startup fullscreen setting, aspect ratio, verbose mode, and output window height.

 

-n, --norm=NORM

The mode to set the tuner to (defaults to NTSC). Valid modes are: · NTSC

· PAL

· SECAM

· PAL-NC

· PAL-M

· PAL-N

· NTSC-JP

 

Οι ρυθμισεις του ειναι στο /etc/tvtime/tvtime.xml αν δεν εχεις ~/.tvtime/tvtime.xml.

OK found it!!!!!! :mrgreen:

 

ηθελε norm=pal-bg

 

δηλαδη:

 

>mencoder tv:// -tv driver=v4l2:width=720:height=576:outfmt=uyvy:device=/dev/video0:input=1:norm=pal-bg:fps=25:alsa:adevice=plughw.0,0:audiorate=44100:amode=1:forceaudio:immediatemode=0 -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=8000:vbitrate=5000:keyint=15:acodec=ac3:abitrate=192:aspect=4/3 -o test.mpg

 

[jim_p]

Τι ειναι η παραμετρος pal-bg και πως το ειχες πριν?

[tritonas00]

το ειδα απο τον vlc καθως και αυτος εβγαζε παραμορφωμενη και πρασινη εικονα.

 

καθως αλλαζα video standards στον vlc (PAL, PAL B/G, PAL D/K, NTSC, SECAM κλπ), εβαλα PAL B/G εδειξε κανονικα.

 

οποτε και στον mencoder υπεθεσα οτι θα ηταν pal-bg, και οντως ηταν.

 

πριν το ειχα σκετο pal (norm=pal)

 

-----------

 

και απο τον mencoder:

supported norms: 0 = NTSC; 1 = NTSC-M; 2 = NTSC-M-JP; 3 = NTSC-M-KR; 4 = PAL; 5 = PAL-BG; 6 = PAL-H; 7 = PAL-I; 8 = PAL-DK; 9 = PAL-M; 10 = PAL-N; 11 = PAL-Nc; 12 = PAL-60; 13 = SECAM; 14 = SECAM-B; 15 = SECAM-G; 16 = SECAM-H; 17 = SECAM-DK; 18 = SECAM-L; 19 = SECAM-Lc;

Aυτό που μου αρέσει ειναι ότι τα λύνεις μόνος σου... :P :P :P :-D :-D
