Initially I thought I could do this using R but quickly I've realised that I would need something else possible working together with R. Is it possible to call FFMPEG from R to do the task (...)

That all changed with GA4, which addressed many of UA’s shortcomings by introducing a completely new way to model website data.

So I know its a fairly big challenge but I want to write a basic movie player/converter in c# using the FFmpeg library.

The current code: delta_timestamp = (int64_t)timestamp - (int64_t)s->last_rtcp_timestamp; treats both timestamps as large positive values, causing wraparound to produce a large negative delta instead of the correct small positive delta. For example, with a 90kHz video clock: - last_rtcp_timestamp = 0xFFFFFF00 (near wraparound) - timestamp = 0x00000100 (after wraparound) - Current result: (...)

When vertical subsampling is in use, the next line is accessed via a[src->linesize[3]], yet a is an uint16_t* for >8 bit formats and linesize is always in bytes, so that this actually uses the second line below the current one.

avformat/matroskaenc: Use native id V_FFV1 instead of V_MS/VFW/FOURCC - Andreas Rheinhardt git.videolan.org Git - ffmpeg.git/rss log

avformat/matroskaenc: Use native id V_FFV1 instead of V_MS/VFW/FOURCC Up until now, our muxer wrote FFV1 in video-for-windows compatibility mode out of concern for old demuxers that only support that (whereas the demuxer accepts V_FFV1). This commit switches to using native mode, because a) V_FFV1 is around long enough so that old demuxers should not be an issue (support in FFmpeg has been added in commit 9ae762da7e256aa4d3b645c614fcd1959e1cbb8d in March 2017/FFmpeg 3.3), b) using native mode uses fewer bytes for the CodecPrivate, c) the VfW extradata is zero-padded to an even length if (...)

How to implement in-browser video editing features in a React app? [closed] - Neeru Singh Newest 'ffmpeg' Questions - Stack Overflow

I'm building a React app that uses AI to generate short videos (reels, explainers, etc.). The generation works well, but I want users to edit the output directly in the browser. Key features I need in the frontend: Add/style captions Trim, split, and reorder clips Sync audio, apply transitions, and preview changes I'm considering a custom React-based editor with drag-and-drop, timeline editing, and real-time playback.
