Need a better understanding of HTML 5 audio/video meta data use and placement
24 juin 2012, par nicozI have spent a significant amount of time researching HTML 5 audio and video, however I am stuck understandong the encoding of the meta data. It seems that in my research, using programs like Handbrake (ffmpeg) it is recommend to check of "web optimized" (also using this type of setting when say exporting from imovie). I have concluded that this has to do with moving the file's meta data to the beginning of the file. This then gives the player/browser the info it requires to play immediately without having to wait to load the entire file.
So here is where I am confused and the questions
Does this only apply to mp4 files ? (I need to also encode/transcode .ogv and .webm)
Where does the mp4 MOOV atom fit into this or is that what people are referring to, when they say move the meta data to the front of the file ? -
How to add telemetry data from a video to jpg file ?
10 septembre 2021, par code0x00I have a 360deg video that is created by Go Pro Fusion and has telemetry data in it. I want to extract the telemetry data and put inside of jpg file.


I am extracting images using ffmpeg :


ffmpeg -i VIDEO.mp4 -r 5 img%d.jpg



How can i extract metadata(including telemetry data) for each frame and put that metadata inside jpg image of that frame.


I tried using


exiftool -ee -a -u -U -TagsFromFile video.mp4 img1.jpg



But all the metadata that appear in video does not appear in image.


I tried this :


exiftool -track1:VideoFrameRate=29.97 img1.jpg 



But getting this warning :


Warning: Sorry, Track1:VideoFrameRate doesn't exist or isn't writable
Nothing to do.



20.00



I get this from video. But unable to set in jpg as mentioned above.


And how to ensure that the images are assigned with the exact GPS data ?

Get video pixel data from Exoplayer in Android
25 février 2018, par Oliver MetzIs it possible to grab the pixel data (e.g. as RGB byte array) from a running video within the ExoPlayer ? Ideally as the real video resolution and not the size as the shown View. I’d want to forward that data to OpenCV for ImageProcessing purposes.
Alternatively I’m looking for a robust (ffmpeg based) Android framework to input videos into OpenCV where the input might be IP-Cameras, local files, online files and online streams.
Any help is appreciated.
