  FFprobe Throws JsonSyntaxException with NumberFormatException on Some Video Files [closed] - Daydreamer067 Newest 'ffmpeg' Questions - Stack Overflow
  I'm using FFprobe through the Java wrapper to analyze video files: FFprobe ffprobe = new FFprobe("pathTo/ffprobe.exe"); FFmpegProbeResult probeResult = ffprobe.probe(fichierTemp.getPath()); This works fine for most files. However, on some video files, I get the following error: com.google.gson.JsonSyntaxException: java.lang.NumberFormatException: Expected an int but was 109893054318340751 at line 160 column 37 path $.chapters[0].id It seems like FFprobe is returning a chapter ID that is a long but it expected an int. How can I handle this situation (...)

  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 == (...)

  m3u8 playback issue with VLC player and ffmpeg [closed] - 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 (...)
