  FFmpeg RTSP Recording: Video Timestamp Does not Match With Recorded MP4 File Timestamp [closed] - lastpeony4 Newest 'ffmpeg' Questions - Stack Overflow
  I'm currently testing by streaming a 30 fps example flv video using a local Happy-Time RTSP server. This is the flv file i am streaming with RTSP: I recorded the video with below ffmpeg command: ffmpeg -i rtsp://127.0.0.1:6555/test30fps.flv -c copy test30fps.mp4 The resulting video appears visually satisfactory, yet there's a discrepancy between the displayed time on the video and the actual duration of the video file. Although the MP4 file duration is correct (endRecordingTimeMs-startRecordingTimeMs= mp4 file duration), the time displayed within (...) -- ,

  HLS audio stream choppy in iOS and Mac Safari - but ok in Chrome, VLC - Elliot Newest 'ffmpeg' Questions - Stack Overflow
  I have an HLS stream that seems to have the audio cut out and then return randomly. This only occurs on iOS devices, and Safari on Mac OS. It works fine on Desktop VLC, but not iOS VLC (as in, the audio never cuts out). More confusing still - if we have multiple developers listening to the same HLS stream on different devices at the same time, we all hear the audio cut out and the return at the same time. So clearly something is wrong with the stream itself. We create a dash stream from FFMPEG, and then create an HLS manifest in parallel. transcoder // Right now this (...)

  Multithreading decoding A/V streams via FFmpeg + JNI + Android NDK causes artifacts - tretdm Newest 'ffmpeg' Questions - Stack Overflow

FFmpeg decoding issues in picture I'll attach the code below to make it easier for you to understand what the problem is: ffwrap.cpp static void *audioDecoderThread(void *arg) AudioDecoder *audioDec = (AudioDecoder*) arg; audioDec->prepare(); audioDec->start(); static void *videoDecoderThread(void *arg) VideoDecoder *videoDec = (VideoDecoder*) arg; videoDec->prepare(); videoDec->start(); // ... void (...) -- FFmpeg decoding issues in picture

  How to apply the same FFMPEG slide transition for every slide in a sequence? - will Newest 'ffmpeg' Questions - Stack Overflow
  I have an ffmpeg command to create an MP4 video from a sequence of N x JPEG slides. That is, I do not know how many slides there are in the sequence, it is just a directory of JPEG-s. I'd like to apply a common slide transition for every slide in the sequence. All the examples I've read seem to need to know how many slides there are before the filter is written. The idea is to use one (simple) transition/filter for every slide. So far the script looks like this: play_duration="-framerate 1/10" # 10 seconds for testing ffmpeg \\ $play_duration \\  (...) -- How to Create a Slideshow from Images using FFmpeg

  How to Terminate a Process Normally Created using ProcessBuilder - Bilal Ahmed Yaseen Newest 'ffmpeg' Questions - Stack Overflow
  I am creating Processes using ProcessBuilder in my Java Application. The created process executes some FFMPEG commands which actually copy the RTSP streams in specified destination media file. ProcessBuilder builder = new ProcessBuilder("ffmpeg", "-i", RTSP_URL, "-f", fileFormat, destFilePath); Process processToExecute = builder.start(); I want to close the process before it completes its execution. So, If I run this FFMPEG command directly in windows CMD and then press 'CTRL+C' after 5 seconds then process get terminates with status '2'. And I (...)

  How to play streaming media of rtmp/rtsp protocol in .NET MAUI Android/iOS? - han zhu Newest 'ffmpeg' Questions - Stack Overflow
  As far as I know, there are many solutions on Windows (winform/wpf). The most typical ones are to call the libvlcsharp and ffmpeg libraries. However, for .NET MAUI Android/iOS, I have not found the corresponding support library at present. In fact, my purpose seems very simple. I want to use MAUI to implement a real-time streaming media player that can support the rtmp/rtsp protocol. Does anyone know of any good solutions? Thanks I tried the MediaElement from the community toolkit but it doesn't support rtmp so I'm hoping to find a solution to support rtmp live streaming in (...)

  Is it still possible to compile modern x264 with the nal long start code used prior to release r1510? - Bryan Knowles Newest 'x264' Questions - Stack Overflow
  I'm currently nerding out on old technology with HD-DVDs. The only freely available muxer is hddvdmux, I'm using MultiAVCHD for this. Beginning with r1510, x264 switched to short start packets for NAL HRD (from what I understand). This makes the stream incompatible with hddvdmux. deank on doom9 patched hddvdmux to accept short start codes, but in doing so, the video file plays too quickly and the audio goes out of sync. The results I'm getting from the 2009 release of x264 leave much to be desired in comparison to modern releases, and I'd like to get those (...)

  How do I include FFMpeg for development in a windows program? - Lama Mao Newest 'ffmpeg' Questions - Stack Overflow
  I'm trying to follow a tutorial about using the FFMpeg libraries to extract frames from videos in C++ (by Bartholomew). In order to include the libraries, according to the tutorial, it is advised to use pkg-config to find the libraries and put them together so that CMake can include them. In the video he uses homebrew to install ffmpeg and somehow pkg-config is able to find the header files for ffmpeg (libavcodec, libavformat, libavdevice ...) The problem is I don't know how to get the ffmpeg libraries installed so that pkg-config can find them. On (...) -- by Bartholomew
