  FFmpeg av_read_frame not reading frames properly? - Sir DrinksCoffeeALot Newest 'ffmpeg' Questions - Stack Overflow
  Alright, so I've downloaded some raw UHD sequences in .yuv format and encoded them with ffmpeg in .mp4 container (h264 4:4:4, 100% quality, 25fps). When i use ffprobe to find out how many frames are encoded i get 600, so that's 24 secs of video. BUT, when i run those encoded video sequences through av_read_frame i only get like 40-50% of frames processed before av_read_frame returns error code -12. So I'm wild guessing that there are some data packages in middle of the streams which get read by av_read_frame and forces a function to return -12. What my questions are, how should i deal (...)

  My Video Filesize Does Not Equal Bitrate x Time - Sixtoo Newest 'ffmpeg' Questions - Stack Overflow
  I'm trying to use ffmpeg to encode some videos with h264. I'm trying to hit a target filesize. My code is: D:\\SOFTWARE\\ffmpeg\\bin\\test\\ffmpeg.exe -i "%~1" -c:v libx264 -preset veryslow -b:v 200k -an "%~n1.mp4" The video is 15 seconds long. So I've read that my filesize should be 200 x 15 (bitrate x duration). But it's not. The filesize is 400kb, when it should be 3000kb. What gives?

  av_seek_frame() Can't seek to the place I want - alexander chen Newest 'ffmpeg' Questions - Stack Overflow
  I want to intercept a frame of my video file, so I used the av_seek_frame function, the timestamp value I tried using timestamp*AV_TIME_BASE and timestamp/(av_q2d(videostream->time_base)*av_TIME_BASE), but no matter what I use Which one, the obtained frame is always not what I want, and it is observed that the frame time that I want is very different (so the accuracy problem of AVSEEK_FLAG_BACKWARD is excluded here).

Is there a way to stop this behavior? I was trying to add a blank 10 second video before and after the original video, (...)

  How can I correctly provide a mock webcam video to Chrome? - doppelgreener Newest 'ffmpeg' Questions - Stack Overflow

From what I understand this means providing a fake webcam video to Chrome using the --use-file-for-fake-video-capture="/path/to/video.y4m" command line argument. It will then use that as a webcam video. However, no matter what y4m file I provide, I get the following error from Chrome running under these conditions: DOMException: Could not start video source code: 0, message: "Could not start video source", name: "NotReadableError" Notably I can provide an audio file (...) -- the Chromium file that explains fake video capture, the example y4m file list, TestRTC

My goal is to create live streaming system, where media server would send fragmented MP4 pieces to browser. The server would buffer input data from RaspberryPi camera, which sends video as H264 frames. It would then mux that video data and make it available for client. The browser would play media data (that were muxed by server and sent i.e. through websocket) by using Media Source Extensions. For test purpose I wrote the following pieces of code (using many examples I found in the (...)

La constante _SUPER_CRON_DELAIS permet d'ajouter un timestamp sur l'appel de cron. Cela vise à ce que le php reçoive vraiment la requête au lieu qu'elle soit interceptée par un varnish "mal configuré" (comme les timestamp qu'on ajoute aux fichiers images) Dans le cas où il y a un cache de ce type et si la valeur de _SUPER_CRON_DELAIS vaut plus que 1, cela divise d'autant la fréquence des appels au cron en cas de grosse fréquentation.

  Direct3d Color space conversion in GPU - eruslu Newest 'ffmpeg' Questions - Stack Overflow
  Creating direct3d surface inYV12 format and rendering video frames in yuv420 format causes a blur video. Seems like there is a smog on video. I think this is because yuv 420 color space format's data range is in 16-235 for Y planes and 16-240 for U and V planes. They are not in range of 0-255. I changed color format to BGRA in CPU by using ffmpeg's sws_scale() function and I created direct3d surface in BGRA format and then displayed video is OK. But cpu consumption is very high due to color space conversion. Is there any way to make color conversion in GPU or is there another way to have (...)

  Error: spawn process ffmpeg ChildProcessError - Karnon Newest 'ffmpeg' Questions - Stack Overflow
  I wanted to make a program like OBS simply. My ideal code behavior is to create a child process in Node.js and execute FFMPEG commands to send a webcam stream to yourtube live RTMP server. However, the actual behavior is caused by an error in the child-process-promise module used in node.js. I've checked several questions, but I don't have enough experience to understand them, and I hope there's a clear solution. I guess it was because I couldn't find the command address of FFMPEG in the Node environment. Or is calling from the socket environment a problem? I checked that the FFMPEG (...)

This is what I have tried: ffmpeg -i audio.ts -vn -acodec copy audio.wav This does return a .wav file, but I'm not sure if what I'm doing is optimal or if there's anything I can do to end up with a file of better quality.

  Is it advisable to use FFMpeg on my local server for video conversion? - Yash Desai Newest 'ffmpeg' Questions - Stack Overflow
  We are starting a video sharing website where users will be able to upload videos in their native formats. However, since video streaming on the web generally is in the FLV format, we need to convert the videos to FLV. Also, the site will be hosted on Amazon EC2 and storage using S3.

  Merging two videos is easy, been answered couple of times. What I have is multiple overlapping videos. A video might have overlaps with video before it. Meaning if video 1 covers 1-5 timeline then video 2 may overlap 1, and cover 3 to 8. Merging them as is would result in 1-5|3-8, when i need 1-8 only. Videos are alphabetically sorted. My general idea of solution is... grab last frame of the video if it's first video continue if it's not first video, ie. 2nd, search for frame saved in previous steps frame by frame if it reaches to last frame of current video then there is no overlap (...)

  How to specify an offset and a seek position for a video stream of a mp4 container? - maximedupre Newest 'ffmpeg' Questions - Stack Overflow

  How to Read DJI H264 FPV Feed as OpenCV Mat Object? - Walter Morawa Newest 'ffmpeg' Questions - Stack Overflow
  TDLR: All DJI developers would benefit from decoding raw H264 video stream byte arrays to a format compatible with OpenCV. I've spent a lot of time looking for a solution to reading DJI's FPV feed as an OpenCV Mat object.

But, when I set GOP size to 2, publish stream to ingest server, consume this stream and measure latency, it is between 0.8-1.2 seconds, not 2+ seconds as excepted. Increasing GOP size leads to same results: with GOP 4 latency is near 2.5 seconds, not 4 seconds.

  FFMPEG caching how to configure and get cache file names - Manity Newest 'ffmpeg' Questions - Stack Overflow
  I am using a c# WPF video player wrapper that uses FFMPEG. It is called FFME MediaElement. Using this i have been able to activate caching in FFMPEG using the "cache" https://www.ffmpeg.org/ffmpeg-protocols.html#cache protocol value. This works and i can see the cache files being created in my application directory as video files are loaded. It seems to create a new cache file each time a video is loaded. The cache file names are of the convention ffcachexxxxxx. Ignoring the wrapper i am using, is there a way (if i was using FFMPEG on its own) to get or determine the cache file name, or (...) -- https://www.ffmpeg.org/ffmpeg-protocols.html#cache

  how to create an http live stream ( broadcast ) from a segmented mp4 without sound defects - user3621958 Newest 'ffmpeg' Questions - Stack Overflow
  tl;dr - concatenating independent short videos to an hls playlist creates sound defects. A 'Tick' sound at the concatenation point. How do I avoid it ? I have a process that emits a 4 second MOV video every 3 seconds. Those 4s videos are segments of a longer video. But they are completely independent. I want to be able to play the Longer video before it exists. In order to achieve that I'm creating an HLS even playlist hls event playlist I first convert the first 4s video to hls using ffmpeg by running : fmpeg -y -i output0.mov -c:a aac -b:a 128000 -r:a 44100 -c:v libx264 -x264-params (...) -- hls event playlist

  I am using a the libav library to record video from a CSI camera on a raspberry pi. I can successfully record the camera data to a file, however I now want to synchronise the frames between two cameras. I've setup a mechanism to synchronise when frames are captured, however I assumed when I called av_read_frame(input_format_context, &packet), that the next frame would be captured. However, it turns out that the video is streamed into some buffer, and when the buffer is full, it waits until the av_read_frame method is called which removes data from the buffer, thus allowing another (...)
