  Image mask blur processing problem using ffmpeg - andrew kim Newest 'ffmpeg' Questions - Stack Overflow
  I want to apply blur using masking to two or more points in the image. I want to use a circular or other type of blur in ffmpeg rather than a box blur. I wrote the ffmpeg code, but an error continued. When there is only one blur, it works correctly, but when there are two or more blurs, an error occurs.

  FFmpeg C++ API : Using HW acceleration (VAAPI) to transcode video coming from a webcam [closed] - nicoh Newest 'ffmpeg' Questions - Stack Overflow
  I'm actually trying to use HW acceleration with the FFmpeg C++ API in order to transcode the video coming from a webcam (which may vary from one config to another) into a given output format (i.e: converting the video stream coming from the webcam in MJPEG to H264 so that it can be written into a MP4 file). I already succeeded to achieve this by transferring the AVFrame output by the HW decoder from GPU to CPU, then transfer this to the HW encoder input (so from CPU to GPU). This is not so optimized and on top of that, for the given above config (MJPEG => H264), I (...) -- https://github.com/FFmpeg/FFmpeg/blob/master/doc/examples/vaapi_transcode.c

  Why does -filter:v fps=60 need re-encoding? - kwjsksai Newest 'ffmpeg' Questions - Stack Overflow
  I mean, let's say 30 fps -> 60 fps. You just need to duplicate frames. Decode a frame and present it at 2 timepoints. I know mp4 can present a frame at different timepoints, right?

In this case, the input video has an FPS of 58 (actually an avg framerate of 57442500/996461 as reported by an ffmpeg probe), and I require the output to match, but ffmpeg overrides me and sets it to 59.9.

  avformat/rcwtdec: add RCWT Closed Captions demuxer RCWT (Raw Captions With Time) is a format native to ccextractor, a commonly used OSS tool for processing 608/708 Closed Captions (CC). RCWT can be used to archive the original extracted CC bitstream. The muxer was added in January 2024. In this commit, add the demuxer. One can now demux RCWT files for rendering in ccaption_dec or interop with ccextractor (which produces RCWT). Using the muxer/demuxer combo, the CC bits can be kept for processing or rendering with either tool. This can be an effective way to backup an original CC stream, (...)

  ffmpeg, how to cut to exactly at the start and end time? [closed] - Wayne Julian Newest 'ffmpeg' Questions - Stack Overflow
  According to this article you can only cut the time, but not specify when to cut from the original video. So the end time will always be wrong. You need to calculate each time on the timeline when your video will end. e.g. -ss 01:30:40 -to 03:03:05 will cut your video in the wrong order, because it starting the calculation not from the 00:00:00 of the video, but from the -ss 01:30:40 Is there a workaround for this? example command: ffmpeg -ss 00:14:15 -an -i "2022-05-30.mp4" -to 01:30:40 -crf 23 -c:v libx264 PART1.mp4 I will lose 14:15 minutes here, it is clearly a (...) -- this article

  configure: simplify bigendian check The preferred way to use LTO is --enable-lto but often times packagers still end up with -flto in cflags for various reasons. Using grep on binary object files is brittle and relies on specific object representation, which in the case of LLVM bitcode, debug information or other intermediary formats can fail silently. This patch changes the check to a more commonly used define for GCC style compilers. More checks may be needed to cover other potential compilers that don't use the __BYTE_ORDER__ define.
