Récupération d’informations sur le site maître à l’installation d’une instance

Are there differences between the parameters of different versions of ffmpeg ?

13 octobre 2019, par Mauro Alejandro Pereira

I want to obtain a different raw video for each frame of an MP4 file.
My instruction works in an old version of ffmpeg but not in the new one.

In the mp4 file there are 137 frames. It is checked. The versions are installed on different machines.

Versions 2.8.15 :

$ ffmpeg -i ./video.mp4 -vf fps=30 -vframes 137 -vcodec rawvideo -s '1920x1080' -pix_fmt gray -threads 0 frame%08d.raw

using ffmpeg.js to play H265 video, only play hvc1 format, can't play hev1 format, is there anyway to play hev1 ?

1er novembre 2019, par Alex

I compiled ffmpeg into ffmpeg.js and ffmpeg.wasm by using emscripten, so that it can run in the browser and play H265 video.

However, I found that only the hvc1 format can be played.
Like that：

Stream #0:0(und): Video: hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, bt709, progressive), 1280x720, 854 kb/s, 25 fps, 25 tbr, 12800 tbn, 25 tbc (default)

and the hev1 format cannot be played.Like that :

Stream #0:0(und): Video: hevc (Main) (hev1 / 0x31766568), yuv420p(tv, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 829 kb/s, 25 fps, 25 tbr, 12800 tbn, 25 tbc (default)

Web browser’s Console has this errors

ffplay can play these two, why can only play hvc1 after compiling into ffmpeg.js and ffmpeg.wasm ?

ffmpeg take input and output as webm on port

I am wondering how I can take an audio input and output it as a webm

This is what I thought would work to get it to rtp out but running into issue.
