  m3u8 playback issue with VLC player - YUZ Newest 'ffmpeg' Questions - Stack Overflow
  I’m creating a timelapse video from a folder of images using FFmpeg, generating two HLS (m3u8) playlists: one at 1080p and another at 2K resolution. The playlists and .ts segments appear to be generated correctly, but when I play the m3u8 files in media players like VLC or PotPlayer, the video does not play seamlessly. Instead, it plays in a segment-by-segment manner (e.g., it stops after each segment and doesn’t automatically continue to the next one). I expect the entire video to play continuously without interruptions. What could be the issue? I ran these commands on cmd: for %i (...)

  Merge multiple hls playlists - Boris Newest 'ffmpeg' Questions - Stack Overflow
  I want to speed up the process of HLS segmentation of .mp4 video. Now, processing a half-hour video can take about 5 minutes, and that is too long. To do this, I decided to split the video into fragments, process each of them in parallel, and then create an .m3u8 file that will contain a list of .ts files from all the resulting playlists in the correct order. I used the next commands: ffmpeg -i original.mp4 -acodec copy -f segment -segment_time 10 -vcodec copy -reset_timestamps 1 -map 0 output_time_%d.mp4 for splitting the original video to .mp4 fragments 10 seconds (...)

  FFmpeg av_seek_frame() successful, but decoding always starts from the beginning - Summit Newest 'ffmpeg' Questions - Stack Overflow
  I'm working on a video player using FFmpeg in C++, where I need to seek to a specific PTS (timestamp) and start decoding from there. However, even after a successful av_seek_frame(), decoding always starts from frame 0 instead of the target frame. void decodeLoop() while (!stopThread) std::unique_lock lock(mtx); cv.wait(lock, [this] return decoding || stopThread; ); if (stopThread) break; int64_t reqTimestamp = requestedTimestamp.load(); // **Skip redundant seeks** if (reqTimestamp == (...)

  Looking for a non-FFMPEG/non-Lame Python audio converter for Android [closed] - Marcelcolt Newest 'ffmpeg' Questions - Stack Overflow
  So as the title suggests, I'm looking for another way to convert audio. I am currently using PyTubeFix to download audio from YouTube. That works awesome, but it downloads in M4A. I would really like it in MP3. Most converter libraries and packages use FFMPEG. I've tried to download it through Termux and PyDroid3, but that doesn't work. I've tried to compile it for Android with NDK, but I am so lost in what I am supposed to be doing... Same goes for Lame. I've been at it for over a week now, but I can't find any other way to convert.  (...)

  FFmpeg WASM Custom build : defining custom flags - Ettur Newest 'ffmpeg' Questions - Stack Overflow
  I wish to create custom ffmpeg.wasm build Now the official GUIDE show four commands "make dev" "make prd" etc So I cloned THE REPO and ran "make prd".

  ffmpeg decoding mixing frames - Paulo Morgado Newest 'ffmpeg' Questions - Stack Overflow
  I'm using FFmpeg.AutoGen in a .NET 8.0 application for decoding H264 and JPEG. Every usage uses its own instance (there are no shared objects) and there isn't simultanous use of each object. However, they can be used from different threads. But I'm getting the encoded results with mixed data from all sources. It happens mostly for the same origin codeec, but not esclusivelly. I have a base class that looks like this: public abstract unsafe class Decoder : IDisposable protected readonly object sync = new(); protected AVCodecContext* (...) -- FFmpeg.AutoGen

  How to restream IPTV playlist with Nginx RTMP, FFmpeg, and Python without recording, but getting HTTP 403 error? [closed] - boyuna1720 Newest 'ffmpeg' Questions - Stack Overflow

FFmpeg: Used to handle the video stream. Python TCP: Trying to handle the connection between my server and the IPTV source. #!/usr/bin/env python3 import sys import (...)
