  FFMPEG My stitched frames colors looks very different from my original video, causing my video to not be able to stitch it back properly - Wer Wer Newest 'ffmpeg' Questions - Stack Overflow
  I am trying to extract some frames off my video to do some form of steganography. I accidentally used a 120fps video, causing the files to be too big when i extract every single frame. To fix this, I decided to calculate how many frames is needed to hide the bits (LSB replacement for every 8 bit) and then extract only certain amount of frames. This means if i only need 1 frame, ill extract frame0.png ill remove frame0 from the original video encode my data into frame0.png stitch frame0 back into ffv1 video concatenate frame0 video to the rest of the video, frame0 (...) -- Frame0.mkv, original.mkv, results.mkv

  How to check 'Output bit depth' of the libx264 library in ffmpeg? - Greg Newest 'x264' Questions - Stack Overflow
  According to the x264 Encoding Guide, the crf scale depends on whether x264 is 8-bit or 10-bit. Supposedly x264 --help shows the Output bit depth. But on Windows ffmpeg -h full doesn't say anything about Output bit depth and the crf scale option is described as from -1 to FLT_MAX. How can I check if my ffmpeg is using 8-bit or 10-bit version of the libx264 library? -- x264 Encoding Guide

  lavc/flacdsp: do not assume maximum R-V VL - Rémi Denis-Courmont git.videolan.org Git - ffmpeg.git/rss log
  lavc/flacdsp: do not assume maximum R-V VL This loop correctly assumes that VLMAX=16 (4x128-bit vectors with 32-bit elements) and 32 >= pred_order > 16. We need to alternate between VL=16 and VL=t2=pred_order-16 elements to add up to pred_order. The current code requests AVL=a2=pred_order elements. In QEMU and on thte K230 hardware, this sets VL=16 as we need. But the specification merely guarantees that we get: ceil(AVL / 2) <= VL <= VLMAX. For instance, if pred_order equals 27, we could end up with VL=14 or VL=15 instead of VL=16. So instead, request literally VLMAX=16. [DH] (...)

  avfilter/af_atempo: Simplify resetting The earlier code distinguished between a partial reset (yae_clear()) and a complete reset (yae_release_buffers() which also releases the buffers); this separation existed to avoid allocations, as buffers were reallocated on reconfigs. Yet it is pointless since a5704659e3e41b7698812b89f67d9a7467a74d20, so simply use yae_release_buffers() everywhere.

  libavcodec/x86/vvc: Add AVX2 DMVR SAD functions for VVC Implements AVX2 DMVR (decoder-side motion vector refinement) SAD functions. DMVR SAD is only calculated if w >= 8, h >= 8, and w * h > 128. To reduce complexity, SAD is only calculated on even rows. This is calculated for all video bitdepths, but the values passed to the function are always 16bit (even if the original video bitdepth is 8). The AVX2 implementation uses min/max/sub. Additionally this changes parameters dx and dy from int to intptr_t. This allows dx & dy to be used as pointer offsets without needing to use (...)

  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 (...)

  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.

  OpenGL to FFMpeg encode [closed] - Ian A McElhenny Newest 'ffmpeg' Questions - Stack Overflow
  I have a opengl buffer that I need to forward directly to ffmpeg to do the nvenc based h264 encoding. My current way of doing this is glReadPixels to get the pixels out of the frame buffer and then passing that pointer into ffmpeg such that it can encode the frame into H264 packets for RTSP. However, this is bad because I have to copy bytes out of the GPU ram into CPU ram, to only copy them back into the GPU for encoding.

  libavcodec/mpegvideo_enc: fix multi-threaded motion estimation rounding for mpeg4 ff_init_me() was being called after ff_update_duplicate_context(), which caused the propagation of the initialization to other thread contexts to be delayed by one frame. In the case of mpeg4 (or flipflop_rounding), this would make the hpel_put functions differ between the first thread (which would be correctly initialized) and the other threads (which would be stale from the previous frame).

  How do I correctly pause and resume recording with ffmpeg without messing with the fps? [closed] - 10typesofpeople Newest 'ffmpeg' Questions - Stack Overflow
  I am recording desktop video and audio with ffmpeg. I am controlling the process with c#. 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.

At each of the following stages, the int16_t array is filled by subtracting an int8_t from the current stage's int16_t array.

  Adding a rotating effect on an image using ffmpeg? [closed] - Garry Newest 'ffmpeg' Questions - Stack Overflow
  I'm trying to overlay an image on a video, and add subtle rotating effects for that image, left, right, left right, and so on. (see pictures) The rotation works, however the edges are always very jagged and bad quality. Is there a way to improve my filters, or is there a better approach that I can use, without jagged edges? This works, overlays the image.png and applies to rotating effect: ffmpeg -loop 1 -i image.png -i video.mp4 -t 10 -filter_complex (...) -- , ,

  How to change pitch and tempo together, reliably with ffmpeg - Ray C Newest 'ffmpeg' Questions - Stack Overflow
  I know how to change tempo with atempo, but the audio file becomes distorted a bit, and I can't find a reliable way to change pitch. (say, increase tempo and pitch together 140%) Sox has a speed option, but truncates the volume AND isn't as widely available as ffmpeg. mplayer has a speed option which works perfectly, but I can't output without additional libraries.

  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.
