I am stuck with FFmpeg.AutoGen G726 Audio codec, it always shows error invalid argument.
Note that I Tried other codecs such as G722, G711 and it is working fine except for G726 codec. I also confirm that my binaries does support G726 codec using this command ffmpeg -formats. Please tell me what could be the reason, and if you know any other library for decoding G726 that would be better

I’d like to extract data from codec string
For example, there is a string like “avc1.64001F”
And it produce data like below.
Codec : H264
profile : High
Level : L3.1

I found this example on GitHub: avio_read_callback.c. Unfortunately, it is a very simplified example because it reads the whole input file into memory and processes it at once.

Hello everyone, I’m working on a project that involves trimming a video using FFmpeg libraries in C++. While I can successfully append and trim the end of the video, I’m facing an issue with trimming the start. The output video is always a correct length clip of a single frame from the original video, rather […]

I’m doing video transcoding live stream. The H264 input stream from the usb camera, I decided to encode the same AVFrame in different threads for streaming x264 with low bitrate and for jpg snapshots, but at some points avcodec_send_frame is successful, at others it returns error -22, and sometimes even Segmentation fault.

I’m working on a C# project where I need to run FFmpeg commands to process videos. The FFmpeg command works perfectly fine when executed directly in the shell, but it hangs when run from my C# application. I suspect the issue is related to the output pipes getting full.

I have a c# application where I have control of an ffmpeg (https://www.ffmpeg.org/) process. I am using it to capture video and audio, either from desktop or webcam. I am using code similar to the answer from this question (How to pause/resume ffmpeg video capture in windows from C# application) to suspend and resume the process. However, while suspended, the captured video extends the frame it was suspended on for the entire duration of the suspension.

I know video files can (and do) contain frames that are encoded out of order, which is why dts and pts exist, but can you send your frames in an arbitrary order, with their correct pts, and expect the video file to play?

I’m recording my screen on Windows using the command: ./ffmpeg -f gdigrab -framerate 30 -i desktop -c:v libx264 -crf 20 -preset ultrafast -max_muxing_queue_size 1024 -hls_time 5 -hls_list_size 10 -hls_flags delete_segments -hls_segment_filename "d:\1\file%03d.ts" "d:\1\playlist.m3u8"

The following code works perfectly as long as I only move the crop rectangle, however as soon as I change its size I no longer get frames out of my filter (av_buffersink_get_frame returns -11). It’s crazy, even after the size changes, if it eventually changes to the original size that frame will go through, then it will go back to no longer providing frames.
