FFMPEG Failed to Connect to UDP Stream in Kubernetes Pod [closed] - Nimrod Newest 'ffmpeg' Questions - Stack Overflow

I have a pod inside my kubernetes (openshift) cluster. The pod tries to connect to a remote UDP video livestream to read frames to be processed.

avutil/csp: Improve enum range comparisons - Andreas Rheinhardt git.videolan.org Git - ffmpeg.git/rss log

avutil/csp: Improve enum range comparisons The underlying integer type of an enumeration is implementation-defined (see C11, 6.7.2.2 (4)); GCC defaults to unsigned if there are no negative values like for all enums from pixfmt.h except enum AVPixelFormat. This means that tests like "if (csp >= AVCOL_SPC_NB)" for invalid colorspaces need not work as expected (namely if enum AVColorSpace is signed). It also means that testing for such an enum variable to be >= 0 may be tautologically true. Clang emits a -Wtautological-unsigned-enum-zero-compare warning for this. Fix both of (...)

Is it possible to embed ffplay? - EthanL Newest 'ffmpeg' Questions - Stack Overflow

ffmpeg's viewer, ffplay, has a lot of great options for optimizing viewing experience. I've been able to get it to nicely display an RTSP stream at low latency. However, it's been difficult to include it in a GUI. Is that possible? Is there a GUI that does that? Note: I am NOT trying to embed in a browser, or just toss the window on top of a GUI. Best solution: desktop GUI that includes ffplay in a widget First alternative: desktop GUI that has variable opacity. If the ffplay window is layered below the GUI, and the GUI is transparent, it could look (...)

Ffmpeg to duplicate an audio stream and encode this new stream - sion Newest 'ffmpeg' Questions - Stack Overflow

I have some video files that I need to re-encode due to compatibility issues. They are currently mkv files with h.264 video and ac3-a52 audio. I want to keep the h.264 video, convert the container to m4v and create two audio tracks, one with the original ac3-a52 and one copied from that but in aac stereo. I assume there has to be some sort of audio stream mapping command but I don't know how to map and re-encode at the same time. What command should I enter into ffmpeg to achieve this? Also, what is the difference between ac3 and ac3-a52? Will an apple TV still be (...)

avcodec/sanm: implement STOR/FTCH for ANIMv1 Handle STOR/FTCH the same way the RA1 game engine does: On STOR, save the next following FOBJ (not the decoded image) in a buffer; decode it on FTCH. The RA1 codecs and the fobj handler now take an explicit GetByteContext in order to be able to replay stored data. Used extensively by Rebel Assault 1 for e.g. backgrounds and the cockpit overlay. For ANIMv2 keep the current system to store the decoded image, as replaying a FOBJ would not work with codecs37/47/48 due to sequence violations. Signed-off-by: Manuel Lauss (...)

A Primer to Ethical Marketing: How to Build Trust in a Privacy-First World - Alex Carmona Piwik

Imagine a marketing landscape where transparency replaces tactics, where consumer privacy is prioritised over exploitation, and where authentic value builds genuine relationships. This isn’t just an ideal—it’s the future of marketing. And it starts with ethical marketing practices. 76% of consumers refuse to buy from companies they do not trust with their data. Ethical marketing has become essential for business survival. As privacy regulations tighten and third-party cookies phase out, marketers face a critical question: how can they balance effective, personalised campaigns whilst (...) -- Marketing, Privacy, ethical marketing

How to stream synchronized video and audio in real-time from an Android smartphone using HLS while preserving orientation metadata? - Jérôme LAROSE Newest 'ffmpeg' Questions - Stack Overflow

Hello, I am working on an Android application where I need to stream video from one or two cameras on my smartphone, along with audio from the microphone, in real-time via a link or web page accessible to users. The stream should be live, allow rewinding (DVR functionality), and be recorded simultaneously. A latency of 1 to 2 minutes is acceptable, and the streaming is one-way. I have chosen HLS (HTTP Live Streaming) for its browser compatibility and DVR support. However, I am encountering issues with audio-video synchronization, managing camera (...)

I'm trying to apply different audio effects, such as making audio sound like a phone call. Below is my current approach. As you can see, I'm using multiple filters and simple algorithms to achieve this effect, but the output quality isn't ideal.

vulkan: take refs of frames using the regular buffer ref path - Lynne git.videolan.org Git - ffmpeg.git/rss log

vulkan: take refs of frames using the regular buffer ref path This simplifies the code, reduces allocations, and critically, does not store references of frames, along with references to hw_frames_ctx. The issue was that storing refs to frames while transferring stored refs to hw_frames_ctx of frames, and so created a circular dependency, which caused the Vulkan device to never be terminated. This only stores what it strictly needs as a dependency, and enables the frames context to be freed, even while doing asynchronous transfers. [DH] (...)
