\n\n\u00a0had the same problem with on a raspberrypi 4 with gstreamer and solved it by enabling the kernel side support (often referenced as “v4l2m2m”).\n\nYou can check it is activated because you get new \/dev\/video character device files in addition to \/dev\/video0. (for me it’s 3 new files \/dev\/video[10,11,12]).\n\nCheck that the kernel module is loaded or load it with:\n
modprobe bcm2835-codec\n<\/code><\/pre>\nThen\u00a0gst-inspect-1.0 video4linux2<\/code>\u00a0should show you the elements you are looking for, such as v4l2h264dec, v4l2h264enc, v4l2vp8dec, …. (sometimes gst-inspect-1.0 does not really retry but relies on a cache which might not reflect recent changes: removing the cache can be helpful. In my install I do\u00a0rm ~\/.cache\/gstreamer-1.0\/registry.armv8-a.bin<\/code>)\n\n<\/div>\n <\/p>\n v4l2-ctl –get-fmt-video -d \/dev\/video2<\/span><\/p>\n modprobe v4l2loopback video_nr=5 card_label=”vcam” exclusive_caps=1<\/span><\/p>\n <\/p>\n https:\/\/www.highvoltagecode.com\/post\/webrtc-on-raspberry-pi-live-hd-video-and-audio-streaming<\/a><\/p>\n Installation for ARM (Raspberry Pi)<\/a><\/blockquote>\n<\/iframe><\/div>\n <\/p>\ngpu_info.sh<\/p>\nvcgencmd version\necho “#########################################”\necho “memory info:”\nvcgencmd get_mem arm && vcgencmd get_mem gpu<\/p>\necho “#########################################”\necho “gpu temperature info:”\nvcgencmd measure_temp<\/p>\necho “#########################################”\necho “gpu clock info:”\nfor src in arm core h264 hevc isp v3d uart pwm emmc pixel vec hdmi dpi ; do\necho -e “$src:\\t$(vcgencmd measure_clock $src)” ;\ndone<\/p>\necho “#########################################”\necho “gpu volts info:”\nfor id in core sdram_c sdram_i sdram_p ; do\necho -e “$id:\\t$(vcgencmd measure_volts $id)” ;\ndone<\/p>\necho “#########################################”\necho “code info:”\nfor codec in H264 H265 HEVC MPG2 WVC1 MPG4 MJPG WMV9 ; do\necho -e “$codec:\\t$(vcgencmd codec_enabled $codec)” ;\ndone<\/p>\n<pre><code><\/code><\/pre>","protected":false},"excerpt":{"rendered":"MJPEG Server (Ubuntu 16.04) gst-launch-1.0 -v filesrc location= \/home\/rein\/Videos\/big_buck_bunny_720...<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[],"class_list":["post-2190","post","type-post","status-publish","format-standard","hentry","category-linux"],"_links":{"self":[{"href":"https:\/\/nick.txtcc.com\/index.php\/wp-json\/wp\/v2\/posts\/2190","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nick.txtcc.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nick.txtcc.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nick.txtcc.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/nick.txtcc.com\/index.php\/wp-json\/wp\/v2\/comments?post=2190"}],"version-history":[{"count":24,"href":"https:\/\/nick.txtcc.com\/index.php\/wp-json\/wp\/v2\/posts\/2190\/revisions"}],"predecessor-version":[{"id":2271,"href":"https:\/\/nick.txtcc.com\/index.php\/wp-json\/wp\/v2\/posts\/2190\/revisions\/2271"}],"wp:attachment":[{"href":"https:\/\/nick.txtcc.com\/index.php\/wp-json\/wp\/v2\/media?parent=2190"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nick.txtcc.com\/index.php\/wp-json\/wp\/v2\/categories?post=2190"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nick.txtcc.com\/index.php\/wp-json\/wp\/v2\/tags?post=2190"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
