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). My code is as follows: double tmp0 = timeStamp/(av_q2d(inputVideoStream->time_base)*AV_TIME_BASE); // double tmp0 = timeStamp * AV_TIME_BASE; code = (...)

FFMPEG Streaming using RTMP - desto Newest 'ffmpeg' Questions - Stack Overflow

I'm trying to create a stream using ffmpeg to send a video to a Red5 Server.

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

I'm trying to run end-to-end testing in Chrome for a product that requires a webcam feed halfway through to operate. 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

Anomalie #4345: super_cron HS en https - jluc - Revisions : SPIP

Il y a en effet plusieurs trucs : une correction de code, une amélioration potentielle et des modifs des commentaires. 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 (...)

Gracefully closing FFMPEG child processes from node - Gordon Newest 'ffmpeg' Questions - Stack Overflow

I am trying to record numerous audio feeds using ffmpeg. Node downloads a config file with the stream URLS (HLS M3U8 playlists), parses it and starts the appropriate number of ffmpeg instances. When I go to shut them down, nothing happens and I have to kill them with task manager, resulting in corrupt files. When I am debugging and hit control-c within a minute or two of starting the program, it works without issue. When I need to record more than 5-10 minutes that I have problems. I found this related question from 2013, and adapted it to fit my multiple stream situation. The recorder (...)

How do I generate a lossless video file with chrome.tabCapture.capture? - Black-Hole Newest 'ffmpeg' Questions - Stack Overflow

Problem Description: chrome.tabCapture.capture will generate a stream, I use MediaRecorder to operate. But MediaRecorder only supports webm video format. Webm video format will compress my recorded video If I recorded the tab page, nothing changed for 10 seconds (including no mouse movement, no sound), the entire web page is still. Then the final webm video file will have only one frame, not even one second. Is there any way to solve this problem?

ffmpeg image + audio to video, file size is very large? - Hoopes Newest 'ffmpeg' Questions - Stack Overflow

After this, I created an executable file for Windows OS using Pyinstaller. However, when I run the executable and try to start the frame extraction process from the GUI, the command prompt pops up, stays for a while and then disappears. This goes on for as long as the extraction process runs. Pyinstaller provides an option for launching the executable without a command prompt using -w option. I've already tried that.
