Allowing downloads of partial video files from Django - DataVis Newest 'ffmpeg' Questions - Stack Overflow

I have a Django app that allows users to make/save 'clips' of video files, that is keep timestamps of start and end times of video files to save in playlists. I would like users to be able to download clips (and playlists as well) they have saved. I have done quite a bit of research on the topic and have gotten ffmpeg working from my terminal to save partial clips (though I've struggled to figure out pathnames for using subprocess.call with ffmpeg), and I have also gotten moviepy working via the terminal to save partial clips. I'm struggling to figure out how to incorporate this into my (...)

How to set a timeout for FFmpegFrameGrabber grab() method in JavaCV - Null Pointer Newest 'ffmpeg' Questions - Stack Overflow

I'm trying to create a player in Java using JavaCV. But .grab() method takes different amounts of time for each grab. How can I discard a grab() operation when it takes too much time? In detail: I'm working on a project to display rtsp streams. To do this, I use JavaCV and its FFmpegFrameGrabber class. Inside a loop I call its .grab() method to grab frames and then I print them on a panel. (Not knowing the reason) grab() method takes much more time in some calls. For example: grab: 15ms, grab: 13ms, grab: 14ms, grab: 95ms, grab: 12ms, ... I wish not to wait for a grab, in case it is (...)

Automatically delete segments (ffmpeg) - luddite478 Newest 'ffmpeg' Questions - Stack Overflow

When i try to delete them, while program is running, ffmpeg is throwing an error, because it need numbers in the file names to stay untouched, so it can increment them properly ("%d"). Is there a way to automatically delete these chunks after N seconds of the stream? Or maybe i can change naming pattern (...)

How to decode in C a stream from this noname almost-UVC grayscale camera - scriptfoo Newest 'ffmpeg' Questions - Stack Overflow

Edit: I found the cause. The stream always begins with something which is not a JPEG. Only after it there is a normal MJPEG stream. Interestingly, not all of the small examples of using V4L2/MJPEG decoders can divide what the camera produces properly into frames. Something called capturev4l2.c is a rare example of doing it properly. Possibly there is some detail, which decides if the camera's bugginess is worked around or not. I have a noname almost-UVC-compliant camera (it fails several compatibility tests). This is a relatively cheap global shutter camera, and thus I would like to use (...) -- a.raw

The browser would play media data (that were muxed by server and sent i.e. through websocket) by using Media Source Extensions. For test purpose I wrote the following pieces of code (using many examples I found in the (...)

Why the size of a decoded package in ffmpeg would be zero? - Mark Newest 'ffmpeg' Questions - Stack Overflow

I was reading the code of decoding a byte stream from a video. But I am a bit confused that the size of packet could be 0 sometimes. What does it mean? And if it is zero, what's the information these bytes carries? int len = av_parser_parse2( pCodecParserCtx, pCodecCtx, &packet.data, &packet.size, cur_ptr , cur_size , AV_NOPTS_VALUE, AV_NOPTS_VALUE, AV_NOPTS_VALUE); cur_ptr += len; cur_size -= len; if (packet.size==0) continue;
