The 428020 part is described in another stack overflow question and this doc, but I have yet to find the corresponding information in the NVENC H264 docs. 8 9 FFmpeg is distributed in the hope that it will be useful, 10. Hope this helps you to solve your problem :) Btw Dont use FFMPEG VAAPI in OBS for Nvidia. I have considered my codec string ( avc1.428020), I am not sure if it corresponds to my encoder. 7 version 2.1 of the License, or (at your option) any later version. What am I missing? Am I using the correct NVENC function? NVENC est une technologie utilisée par NVIDIA permettant lencodage matériel de la vidéo. When I run the setup I get the error: Failed to execute 'configure' on 'VideoDecoder': Failed to parse avcC.įrom what I understand from the documentation the error refers to the dataFromEncoder being wrong in some way.

Where dataFromEncoder is an the following array obtained from the NVENC NvEncGetSequenceParams function: My decoder configuration setup looks like this: let decoderConfig = ĭscription = new Uint8Array(dataFromEncoder) I want to decode frames of that stream using the WebCodecs API in Google Chrome. I have an H264 NVENC Encoder setup which encodes a video stream.
