how to use the H264 video encoder with ffmpeg / opencv2 ?
30 août 2023, par VinceI am on ubuntu 22.04.


I installed ffmpeg with apt.


I am creating a video from some image files using python/opencv2 (installed via pip)


When I use :


cv2.VideoWriter_fourcc(*"mp4v")



the video is successfully created, but is not supported by firefox.


I read online that the H264 encoder would be a better fit for web-browsers supports.


ffmpeg -codecs | grep h264 



shows :




DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders : h264 h264_v4l2m2m h264_qsv h264_cuvid ) (encoders : libx264 libx264rgb h264_nvenc h264_omx h264_qsv h264_v4l2m2m h264_vaapi nvenc nvenc_h264 )




but


cv2.VideoWriter_fourcc(*"h264")



results in :




OpenCV : FFMPEG : tag 0x34363268/'h264' is not supported with codec id 27 and format 'mp4 / MP4 (MPEG-4 Part 14)'




I could not find online what was wrong (h264 is not installed, how to install it ? the 'fourcc' of h264 is not 'h264' ? I should not create a *.mp4 file ?)

How can I download a video with url beginning with blob:https://…
11 août 2017, par iMaxI would like to know if it is possible to download a video from a URL beginning with blob :
blob:https://www.xyz123…
i would prefer a terminal solution (ffmpeg ?, youtube-dl ?). but i have not found anything on the world wide web.
Again : I have the url of the video stream, which looks like the above. How can I download the complete video ?
Update
Ok. I now found a webpage which allowed me to download the video file I wanted :
https://video-download.online/But I am still wondering if there is a Terminal solution for downloading video with blob-URL (like in arte mediathek [ example arte ] or in zdf mediathek [ example zdf ]).
Does nobody know how to do it ?
