  Can I use t with drawbox to simulate a playhead over a waveform in a generated video? - terrorrussia-keeps-killing Newest 'ffmpeg' Questions - Stack Overflow
  I want to simulate a playhead moving over a waveform, like when playing a track in an audio editor. As far as I understand, I can generate this effect if I have both the audio file and an image of the waveform. declare -r DURATION=$(ffprobe -i audio.flac -show_entries format=duration -v quiet -of csv="p=0") ffmpeg -hide_banner -loop 1 -framerate 30 -i waveform.png -i audio.flac \\ -filter_complex " drawtext=text='%pts\\\\:hms -- %n -- %pts\\\\:flt':x=32:y=32:fontsize=24:fontcolor=blackⓐ0.75:box=1,  (...)

  How to test audio mp3 files - صلي علي محمد - Atef Farouk Newest 'ffmpeg' Questions - Stack Overflow
  I am wondering if there is any offline tool that can test audio files and detect positions that have problems like ( long silent, missing codecs, high echo, ...). I expect lame or ffmpeg can do so. or may be python script.

  How do I create an m3p file with the output of the Mac "say" command? [closed] - Oussama L. Newest 'ffmpeg' Questions - Stack Overflow
  I want to read a very long text with the SAY mac's command (say -f file.txt), and to record the output to file.mp3. I thought about using ffmpeg to record all of it, but then i'll need to wait for all the reading process to complete.. I don't really need to listen to it, so if there is a way to directly have an mp3 file just by hitting enter, it would be great..

  Using FFMPEG to join two MTS files together [closed] - Reado Newest 'ffmpeg' Questions - Stack Overflow
  I have two MTS video files, each one 2 minutes long. I need to be able to join the files together and convert the format to MPEG4. 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 cutting around keyframes is not accurate - swwind Newest 'ffmpeg' Questions - Stack Overflow
  TL;DR: I have a large video that requires transcode to play in browser, rather than using -f hls generate every segments into disk, I want to listen to segment request and generate them on demand. However, cutting using -ss and -to is always not accurate among segments, causing video to glitch at segment borders. Here is the details. First know the video's keyframes timestamps. Like below $ ffprobe -fflags +genpts -v error -skip_frame nokey -show_entries format=duration -show_entries stream=duration -show_entries packet=pts_time,flags -select_streams v -of csv (...)

  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 (...)
