FFMPEG hiba élő kamara kép Ubuntu alatt

Fórumok

Üdvözlet!

Sajnos egy teljes rendszer frissítés (oprendszer/kernel) betett az eddig működő élő kameraképnek. :(

A hibák, amiket kapok a script lefuttatásakor:

Hol lehet a hiba, és hogyan lehet orvosolni?

Előre is köszönöm a sok sok segítséget!!!

-pix_fmt yuv420p

és a

[swscaler @ 0x55974da39700] deprecated pixel format used

közötti összefüggést kellene megvizsgálni közelebbről.

Én még első körben, tesztképpen kikapcsolnám a hardveres gyorsítást is, kivenném az ffmpeg paraméterei közül. Azt nem látom, hogy hányas Ubuntu. Az NV driver és kernel verziója jónak tűnik, elég friss, a többi változó (pl. mesa verzió, böngésző verziója) nem ismert az egyenletben. Sőt, ahogy nézem, egy régi Java/Flash-es webmegoldásról van szó, amit feltehetőleg már rég nem gondoznak.

És a hardveres gyorsítást kivetted próbaképp? Azaz az hwaccel kapcsolót, meg a kódeknél az _nvenc részeket törölni kell. Lehet lassú lesz, meg procizabáló, ez most nem is lényeg, csak hogy működésre lehet-e így bírni, mert akkor biztosan tudnánk, hogy a hardveres gyorsítás miatt nem megy.

ffmpeg -an -rtsp_transport tcp "${RTSP}" -pix_fmt yuv420p -vcodec h264 -c:v h264 -r 25 -s:v 1280x720 -b:v 1024k -f flv "${RTMP}" --> így gondoltad?

Igen, így gondoltam, vagyis olyan formában, hogy működjön. Nem tudom melyik kapcsoló kéne neki, megadjuk milyen formátumban lesz a célvideó streamje. Elvileg meg van neki adva a kódeknél, hogy h264, meg a formátumnál flv, de ha így se akarja a tutit, akkor nincs ötletem.

Első körben kipróbálnám, hogy rtmp kimenet helyett csak mp4 vagy mkv teszt file-ba mentsen el egy rövid videót (pl.: 30 mp).

A -loglevel paraméterrel (pl.: -loglevel debug) megnézném megjelenik-e valami releváns információ.

Ekkor ffprobe tool-al és valami lejátszóval (vlc, ffplay, mplayer) bele néznék, hogy sikerült-e a mentés.

Ha nem sikerült, akkor kipróbálnám egy másik codec-el. Ha azzal megy, akkor az nvidia hw encoder-el van valami gond.
