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 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). # ./ffmpeg -hide_banner -codecs | grep h264 DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: (...) -- as I understood from what was written here

ffmpeg does not exit when pipe is closed? - Thomas Newest 'ffmpeg' Questions - Stack Overflow

If this has already been brought up, I apologize. This is part of a software tuner package I am writing as a POC. It is used by Plex Media Server. For the most part, it works with good picture quality but leaves ffmpeg processes when the User clicks "Stop" or closes the browser, I assume plex is closing the socket and that ffmpeg is not erroring out, but I am not sure. this is part of a function where I pass in a TCP Client Network Stream. TCPListener waits for a call, when it accepts one, it passes the network stream off to this function below. When the TCP Client disconnects, (...)

Can I use HTTP/2.0 for downloading HLS streams using FFmpeg? - SpongeBed Newest 'ffmpeg' Questions - Stack Overflow

I am trying to download an HLS stream using FFmpeg. However, FFmpeg defaults to HTTP/1.1 for downloading content, and the video source's firewall blocks HTTP/1.1 connections.

FFmpeg lavfutils.h seems to be missing - Collin Newest 'ffmpeg' Questions - Stack Overflow

The lavfutils.h file is missing from the include folder where the ffmpeg library was put. I installed the ffmpeg library to load an image in c++. I installed it using ./vcpkg ffmpeg. The ff_load_image function is in lavfutils.h, but that file is missing from the ffmpeg_x64-windows folder where vcpkg put the rest of the library. Has the way you load images changed? Or have I installed ffmpeg incorrectly?

checkasm: disable unaligned access emulation - Rémi Denis-Courmont git.videolan.org Git - ffmpeg.git/rss log

checkasm: disable unaligned access emulation The OS may silently fix (emulate) unaligned hardware access exceptions. This is extremely slow and code should be fixed not to rely on unaligned access on affected hardware. Accordingly this requests that the OS disable emulation and instead throw Bus error, which will be caught by checkasm's signal handler. This has no effects if the hardware supports unaligned access in hardware, since no exceptions are generated. prctl() will fail safe in that case. [DH] (...)

lavc/vp8dsp: add R-V V vp7_idct_dc_add4y - Rémi Denis-Courmont git.videolan.org Git - ffmpeg.git/rss log

lavc/vp8dsp: add R-V V vp7_idct_dc_add4y As with idct_dc_add, most of the code is shared with, and replaces, the previous VP8 function. To improve performance, we break down the 16x4 matrix into 4 rows, rather than 4 squares. Thus strided loads and stores are avoided, and the 4 DC calculations are vectored. Unfortunately this requires a vector gather to splat the DC values, but overall this is still a win for performance: T-Head C908: vp7_idct_dc_add4y_c: 7.2 vp7_idct_dc_add4y_rvv_i32: 2.2 vp8_idct_dc_add4y_c: 6.2 vp8_idct_dc_add4y_rvv_i32: 2.2 (before) vp8_idct_dc_add4y_rvv_i32: 1.7 (...)

This reproducible with FATE's vc1_ilaced_twomv test case. The new "pessimist" code can trivially be shared for 16x16 pixel arrays so we also do that.

tl;dr I am trying to merge two videos using concat command. The videos merge well but the audio is missing. I get a warning message about "New audio stream with inder 1 at pos7354 and DTS 15s" which is exactly the time where the second video starts. I don't care about the audio stream from the first video, it is just a thumbnail, but I want the second video audio to work. I merged the files using: ffmpeg -i list.txt -c copy output.mp4

I attempted to upload and compress a video using ffmpeg.js. However, it appears that this process is ineffective on modern browsers. I have already implemented console logging to verify if the video compression is occurring, yet thus far, no compression has been achieved. Could anyone suggest an alternative library for video compression that might better suit the requirements? import FFmpeg from 'ⓐffmpeg/ffmpeg'; export default methods: async handleFileInputChange(event) const file = (...)

Decoding pcm_s16le with FFMPEG? - Davide Caresia Newest 'ffmpeg' Questions - Stack Overflow

i have a problem decoding a wav file using ffmpeg. I'm new to it and i'm not quite used to it. In my application i have to input the audio file and get an array of samples to work on. I used ffmpeg to create a function that gets in input the path of the file, the position in time where to start to output the samples and the lenght of the chunk to decode in seconds. I have no reputation, so I had to make a gdrive directory where you can see the problem and the files on which I worked. Here it is: https://goo.gl/8KnjAj When I try to (...) -- https://goo.gl/8KnjAj

For H.265, the assumption that FFALIGN(width, 16)xFFALIGN(height, 16) is the video resolution can be wrong, since the encoder can use CTU larger than 16x16.

avformat/mov: avoid seeking back to 0 on HEVC open GOP files - llyyr git.videolan.org Git - ffmpeg.git/rss log

avformat/mov: avoid seeking back to 0 on HEVC open GOP files ab77b878f1 attempted to fix the issue of broken packets being sent to the decoder by implementing logic that kept attempting to PTS-step backwards until it reached a valid point, however applying this heuristic meant that in files that had no valid points (such as HEVC videos shot on iPhones), we'd seek back to sample 0 on every seek attempt. This meant that files that were previously seekable, albeit with some skipped frames, were not seekable at all now. Relax this heuristic a bit by giving up on seeking to a valid point (...)

B2B Marketing Attribution Guide: How to Master It in 2024 - Erin Piwik

The last thing you want is to invest your advertising dollars in channels, campaigns and ads that don’t work.

In this guide, we break down what B2B marketing attribution is, how it’s different, which tools you can use to set it up and the best practices. What is B2B marketing attribution?

how to creating V210 encoder in pure c/c++ code [closed] - mans Newest 'ffmpeg' Questions - Stack Overflow

I am trying to implement V210 video encoding by writing the encoder by myself in c/c++ and not using any library. To achieve this, I am trying to see how I can create frame data and then use FFMPEG to put the frames in a video container using this command ffmpeg -s 1280x720 -f v210 -i frames.bin -c:v copy sample_video.mkv to create the frames.bin, I am creating a list of blocks based on the specifications that I found above. The code that I am using to pack YUV to the block is as follows: #pragma pack (push,1) class V210Block public: (...) -- V210 video encoding

How to stream lossy audio in chunks? [closed] - Adam Newest 'ffmpeg' Questions - Stack Overflow

On the client side, I'm collecting periodically received audio slices into a circular buffer during the playback to avoid having to receive the entire file at once, only a small portion of its size. On server side I tried splitting MP3/M4A/OGG into frames, but even with ffmpeg, a gap is created in the chunk (usually at the beginning/end), which prevents me from validly concatenating them on the client side. Not even when I encoded the MP3 to PCM beforehand and then split the WAV file into MP3 chunks. Of course, split to WAV chunks there is no gap, but one slice is larger than (...) --
