  Can ffmpeg show a progress bar? - Pawan Rao Newest 'ffmpeg' Questions - Stack Overflow
  I am converting a .avi file to .flv file using ffmpeg. As it takes a long time to convert a file I would like to display a progress bar. Can someone please guide me on how to go about the same. I know that ffmpeg somehow has to output the progress in a text file and I have to read it using ajax calls. But how do I get ffmpeg to output the progress to the text file?

  How FPS reduction for H264 without transcode? [duplicate] - Александр А Newest 'ffmpeg' Questions - Stack Overflow
  There is a USB camera that sends H264 frames with a frequency of 30 fps in a resolution of 1920x1080, GOP size 30 or 60 (1 or 2 I frame per second depending on the camera and only P-frames), which requires throughput of about 6 mbit/s. It is necessary to reduce this to no more than 2 mbit/s. All this is done on a weak ARMv7, so the option of transcoding is extremely resource intensive, especially considering that I did not find how to do it as a GPU Mali (NanoPi Neo Core). Given that the basic functionality is performed on the framework ffmpeg, is it possible to reduce the frame (...)

  How to stream only a part of a video without downloading the whole thing? - Abbas Newest 'ffmpeg' Questions - Stack Overflow
  I am building a YouTube video trimmer, and currently, it takes the YouTube video ID, downloads the whole video from the server (Even it is like 10 hours long), and then it trims it according to user's inputted timeframe using ffmpeg. Now the problem with this is that it takes so much time to download the whole video even if we want a small piece of it hence it is highly impractical.

  FPS reduction for H264 [closed] - Александр А Newest 'ffmpeg' Questions - Stack Overflow
  There is a USB camera that sends H264 frames with a frequency of 30 fps in a resolution of 1920x1080, GOP size 30 or 60 (1 or 2 I frame per second depending on the camera), which requires throughput of about 6 mbit/s. It is necessary to reduce this to no more than 2 mbit/s. All this is done on a weak ARMv7, so the option of transcoding is extremely resource intensive, especially considering that I did not find how to do it as a GPU Mali. Given that the basic functionality is performed on the framework ffmpeg, is it possible to reduce the frame rate, ideally to 10 fps, WITHOUT loss of (...)

  How do I correctly pause and resume recording with ffmpeg without messing with the fps? [closed] - 10typesofpeople Newest 'ffmpeg' Questions - Stack Overflow

Simplified, my ffmpeg arguments are "ffmpeg -f gdigrab -framerate 30 -i desktop -preset ultrafast -pix_fmt yuv420p output.mp4" I have some functionality to pause and resume the recording, essentially just suspending and resuming the process. This works, however, it leaves the paused section in the video, just one frame for the entire duration. To fix this, I added "-vf setpts=N/FR/TB" yo the arguments.

  Specify percentage instead of time to ffmpeg - user779159 Newest 'ffmpeg' Questions - Stack Overflow
  To get a thumbnail from an image halfway through the video I can do ffmpeg -ss 100 -i /tmp/video.mp4 -frames:v 1 -s 200x100 image.jpg. By using -ss 100 it gets a thumbnail at 100 seconds (which would be halfway through the video assuming the video is 200 seconds long). But if I don't know the exact length of the video, in my application code I would need to use something like ffprobe to first determine the length of the video, and then divide it by 2 to get the thumbnail time. Is there a way to get ffmpeg to get the thumbnail at the percentage of the video you (...)

  Python library to extract metadata from video file stored in variable, rather than on filesystem - Adam J. Kessel Newest 'ffmpeg' Questions - Stack Overflow
  Is there a standard solution for extracting metadata (like aspect ratio, codec, etc) from video data stored in a Python variable, rather than from a file on disk? I see people point most often to ffmpeg-python for video metadata analysis, but as far as I can tell, it can only operate on a filename rather than an object in memory.

  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 (...)

  I would like to convert a jpg file into an avif file that is to be saved in HDR10-capable metadata (PQ curve, 2020 color space, 10 bit).

I want to play with inverse tone mapping, to manipulate the output, so I implemented in Python via subprocess.

  Improving Performance and Quality of Screen Streaming(Headless) with FFMPEG and NVIDIA Hardware Acceleration [closed] - Dhairya Verma Newest 'ffmpeg' Questions - Stack Overflow
