  Using FFMPEG to join two MTS files together [closed] - Reado Newest 'ffmpeg' Questions - Stack Overflow

I have a suitable command line for converting MTS to MP4 but don't know how to join the files together in the first place. Some articles on the web suggest using the CAT command, like: cat video1.mts video2.mts > whole_video.mts However this doesn't work and according to FFMPEG, "whole_video.mts" is only 2 minutes long, not 4 minutes. Does anyone know how to join the files together? Is FFMPEG the best (...)

  Convert video to HLS in iOS app without triggering GPL (FFmpegKit alternative?) [closed] - Aziz Bibitov Newest 'ffmpeg' Questions - Stack Overflow
  I'm building an iOS app in Swift that needs to convert local video files to HLS format (.m3u8). Initially, I used the ffmpeg-kit-ios-full-gpl package from FFmpegKit, which works well. However, since this build includes GPL-licensed components (such as libx264), I'm concerned that using it would require my app to be released under the GPL, which is not compatible with App Store distribution. That said, my needs are fairly basic: I only need to convert H.264 .mp4 video files into HLS format. My Questions: Is there a safe way to use FFmpegKit—such as the (...)

  What codec in OpenCV can do a stronger compression than default 'mp4v'? [closed] - ullix Newest 'ffmpeg' Questions - Stack Overflow
  My project does video recording from a microscope camera, and one experiment can run for days and even weeks. This takes plenty of filespace, so I want as strong a compression as possible. Quality is not a major concern. Currently I use the default 'mp4v' codec with opencv on Python. It works. I tried all codecs Google could find, and surprisingly, only very few worked. And those few that did work were even worse in compression. Where is the limitation? Is it Opencv (4.11.0.86)? Is it FFMPEG (7.1.1)? Is it the distribution (Ubuntu Mate 25.04)? Is it the CPU (AMD (...) -- https://www.youtube.com/watch?v=wW8w2Pppnng

  FFmpeg WASM Compilation with Hardware-Accelerated H.264/HEVC Decoding - gt-devel Newest 'ffmpeg' Questions - Stack Overflow
  I'm working on a media processing SDK with a substantial C++ codebase that currently uses FFmpeg for video decoding on native platforms (Windows/Linux). I need to port this to browsers while preserving both the existing C++ architecture and performance characteristics. The WASM approach is critical for us because it allows leveraging our existing optimized C++ media processing pipeline without a complete JavaScript rewrite, while maintaining the performance benefits of compiled native code. The Challenge: WebAssembly runs in a browser sandbox (...)

  Is there a way to force FFMPEG to decode a video stream with alpha from ​a WebM video encoded with libvpx-vp9? - David Newest 'ffmpeg' Questions - Stack Overflow
  I have a ​WebM file with one video stream that was encoded with VP9 (libvpx-vp9). I wrote a C++ program to extract the frames from the video stream and save them out as PNG's. This works fine except that the resulting PNG's are missing alpha. If I extract the frames from the same WebM file using FFMPEG the resulting PNG's do contain alpha. Here is the output from FFMPEG: $ ffmpeg -c:v libvpx-vp9 -i temp/anim.webm temp/output-%3d.png [libvpx-vp9 ⓐ 0000024732b106c0] v1.10.0-rc1-11-gcb0d8ce31 Last message repeated 1 times Input #0, (...)

  Randomly extract video frames from multiple files [closed] - PatraoPedro Newest 'ffmpeg' Questions - Stack Overflow
  I have a folder with hundreds of video files (*.avi), each one with more or less an hour long. What I would like to achieve is a piece of code that could go through each one of those videos and randomly select two or three frames from each file and then stitch it back together or alternatively save the frames in a folder as jpegs. Initially I thought I could do this using R but quickly I've realised that I would need something else possibly working together with R. Is it possible to call FFMPEG from R to do the task (...)
