سلام
وقتی که دستور
sudo rmmod v42loopback
رو میزنم این خطا میاد:
rmmod: ERROR: Module v42loopback is not currently loaded
میخوام مشکلات v42loopback رو حل کنم تا iriun webcam بدون مشکل بالا بیاد که اونم خطای v42loopback missing رو میده
پیشاپیش از پاسخگوییتون متشکرم
سلام و وقت بخیر.
ماژول مربوطه احتمالا نصب نیست یا لود نشده. با این دستور اگر نصب نباشه میتونید نصبش کنید.
sudo pacman -S v4l2loopback-dkms dkms linux-headers
پس از نصب می تونید لودش کنید:
sudo modprobe v4l2loopback exclusive_caps=1
در صورتی که بازم خطا داشت خروجی دستور زیر رو بفرستید:
dmesg | tail -n 200
هر دو تا دستور اول رو زدم بعد دستور آخری رو زدم این خطا رو داد:
dmesg | tail -n 200
dmesg: read kernel buffer failed: Operation not permitted
دستور آخر رو با sudo بزن.
سیستم رو هم یکدور بهروزرسانی کن؛ اگر کرنل بهروز نباشه و نسخه جدیدی از ماژول رو نصب کنی کار نمیکنه.
اول سیستم رو بروزرسانی کردم با دستور
sudo pacman -Syu
بعد اومدم سراغ این که بعد dkms و اینا ها به ریخت چون dkms نسخه قدمی بود برای 6.18.2_arch2_1 بعد دستی بروزرسانی کردم همین dkms رو به 6.18.9_arch1_2
sudo dmesg | tail -n 200

لطفاً از این به بعد لاگهای طولانی رو داخل PasteBin بذارید و بفرستید.
مشکل خاصی نداره ماژول v4l2loopback توی لاگ شما و لود شده توی کرنل.
خب با این دستور ببینید که لود شده یا نه:
lsmod | grep v4l2loopback
اگر خطای پرمیشن داد با sudo اجراش کنید.
به احتمال زیاد مشکل از برنامه باشه.
lsmod | grep v4l2loopback
v4l2loopback 73728 0
videodev 397312 1 v4l2loopback
زدم اینو داد
برنامه رو هزار بار حذف کردم با pacman -Rns دوباره نصبش کردم.
تو دفعه های قبل برنامه همینم نمیاورد فقط ی صفحه خاکستری
خب این یعنی ماژول لود شده، مشکل از برنامتونه.
خب چی کار کنم هزار بار uninstall کردم و دوباره نصب کردم نشد که نشد
فکر نکنم این اهمیتی داشته باشه، مثل ویندوز نیست که رفتار متفاوتی از خودش نشون بده هردفعه.
یا باید صبر کنید اپدیت بشه برنامه، یا از جایگزین هاش استفاده کنید.
الان نمیتونم کاری کنم؟
بجز جایگزین چون در شرایط حال حاضر نمیشه کاری کرد
نه، چون مشکل از ماژول نیست
پس الان باید برم به خوده پشتیبانی اپ بگم؟!
اگر دسترسی دارید بله.
چون این فورک از یک برنامه دیگست به نظر همون برنامه اصلیه رو نصب کنید بهتره.
و خب فروم هم برای چت کردن نیست و زیادی این تاپیک شلوغ شده.
مرسی ممنون
