• 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

  12 octobre 2019, par RussellHarrower

  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.

• Join a lot of frames with some audio files

  30 octobre 2019, par Laurin Neff

  What I’m trying to do

  I have 3697 frames (frames/[0-3696].png) and 5 audio files, which are the same length in total as the resulting video should be (audio/[0-4].mp3). I’m trying to play the frames at 15 fps, with the audio files playing in sequence and putting this into out.mp4. How can I achieve this ?

  File tree

  frames
  
  |-0.png
  
  |-1.png
  
  |...
  
  |-3695.png
  
  \-3696.png
  
  audio
  
  |-0.mp3
  
  |-1.mp3
  
  |-2.mp3
  
  |-3.mp3
  
  \-4.mp3

  What I’ve tried

  ffmpeg -i frames/%d.png -i audio/%d.mp3 -vf fps=15 out.mp4

  What I expect

  I expect out.mp4 to contain all frames, with the 5 mp3 files playing in sequence

  What actually happens

  $ ffmpeg -i frames/%d.png -i audio/%d.mp3 -vf fps=15 out.mp4
