Like OBS Studio 28.1.1 shortly before, FFmpeg now also uses the two 8th generation video engines supported by NVENC, offered by the top model of the GeForce RTX 4000 series (“Nvidia Ada Lovelace”). General AV1 encoding and decoding via FFmpeg is now supported on the latest Nvid...
I quite enjoyed using hardware encoding with ffmpeg and my AMD Ryzen 5 2400G. Today I did what I assumed I always did and despite of seeing no error messages from ffmpeg I get a file with sound but with no video (mpv or vlc). The encoding: === /mnt/Data_bb/sda8/makepkg/ffmpeg-...
Describes an issue when trying to encode using hardware resulting in errors for each type of supported codec Description Using the FFmpeg 6.0 application for encoding hevc_qsv returns error: "[hevc_qsv @ 0000024068a7aec0] Unknown FrameType, set pict_type to AV_PICTURE_TYPE_NONE.8.93x" and ...
序言从一个 FFmpeg 初学者视角,给你分享我一步步学习深入的历程,不断更新。闲话不多说,直接看正文!走起! 一、FFmpeg介绍与安装1、什么是FFmpegFFmpeg 的全称是“ Fast Forward Moving Picture Expert Group”…

上面的AV_HWDEVICE_TYPE_CUDA就是笔者目前正在做的CUDA是NVIDIA的硬件加速库,AV_HWDEVICE_TYPE_QSV则是以前做的QSV是Intel提供的一套集显上的硬件加速方案。 那么,究竟要怎么知道系统当前的FFMPEG究竟支持哪些硬件库? 可以通过命令行查看:ffmpeg -hwaccel。在hardware acceleration methods:下面可以看到当前FFMPEG集成的硬...
2.3.2 FFmpeg 的音频编码过程 (Audio Encoding Process in FFmpeg) 在FFmpeg 中,音频编码过程主要包括以下步骤: 打开编解码器:使用avcodec_open2函数打开指定的编解码器。 准备音频帧:创建AVFrame结构体,填充音频数据和相关参数。 编码音频帧:使用avcodec_send_frame和avcodec_receive_packet函数将音频帧编码为音频包。
to perform multimedia processing. This allows to use dedicated hardware to perform demanding computation while freeing the CPU from such computations. Typically hardware acceleration enables specific hardware devices (usually the GPU) to perform operations related to decoding and encoding video streams, or...
