• ffmpeg encoding plays very fast. Audio.mp4 and Video.mp4 work, but both together don't

  25 février 2013, par Peter.O

  In both steps 3 and 4 below, the .mp4 plays normally. However, although I've used what seems to be the same settings in the last step (audio + video), that step does not work. The video plays more than 10 times too fast... also the audio does not play.

  The ffmpeg messages for step 5 show that it has included audio.

  Output #0, mp3, to '/tmp/test.mp4':
  
      Stream #0.0: Video: libx264, yuv420p, 720x480, q=2-31, 90k tbn, 23.98 tbc
  
      Stream #0.1: Audio: libmp3lame, 48000 Hz, stereo, s16, 128 kb/s

  Subsequently running ffmpeg -i shows no trace of the audio, but it does report on the video... What have I missed, to get it muxed properly ?...

  #!/bin/bash
  
  
  
  # 1. create Audio 
  
  wine avs2pipe.exe audio "$src_avs" >"$temp_pcm"
  
  
  
  # 2. create Video 
  
  wine avs2yuv.exe "$src_avs" - |
  
    x264 --stdin y4m --output "$temp_h264" - 2>/dev/null
  
  
  
  # 3. This works.  (audio only)
  
  # encode `audio.mp4 
  
  ffmpeg -acodec pcm_s16le -f u16le -ac 2 -ar 48000 -i "$temp_pcm" \
  
         -acodec libmp3lame -f mp3 -ar 48000 -ab 128k  -y "$audio_mp4"
  
  
  
  # 4. This works.  (video only)
  
  # encode `video.mp4 
  
  ffmpeg -i "$temp_h264" \
  
         -vcodec copy -y "$video_mp4"
  
  
  
  # 5. This DOES NOT work!  It plays very fast.
  
  # encode `final.mp4' 
  
  ffmpeg -acodec pcm_s16le  -f u16le  -ac 2 -ar 48000  -i "$temp_pcm" \
  
         -i "$temp_h264" \
  
         -acodec libmp3lame -f mp3 -ar 48000 -ab 128k \
  
         -vcodec copy \
  
         -y "$final_mp4"

• Revision f297504f2d : Re-work configure interface for encoding based on external mi This commit refin

  14 juillet 2014, par Jingning Han

  Changed Paths :
   Modify /vp9/encoder/vp9_encoder.c

  
   Modify /vp9/vp9_cx_iface.c

  
   Modify /vpx/vpx_encoder.h

  
   Modify /vpxenc.c

  
  
  Re-work configure interface for encoding based on external mi

  This commit refines the configuration interface for encoding
  process based on external mode info. It allows the vpxenc to read
  the external file name from command line, and to produce warning
  message when necessary.

• RTSP authentification through ffmpeg/ffplay doesn't work because of special symbols in the password

  26 octobre 2018, par Eugene Mart

  I have run into a problem while trying to receive a video from an IP-camera using ffplay.

  My rtsp request looks like this : rtsp ://login:M3%LOL$KEKfp@x.x.x.x/path/to/media.amp

  And ffplay/ffmpeg returns an 401 Unauthorized error code. I am absolutely sure that the credentials are correct. The problem is caused by the password (M3%LOL$KEKfp), which consists of special symbols like %, and #. Is there any way to make it work without changing the password ?

  I tried using quote marks like this ffplay "rtsp ://login:M3%LOL$KEKfp@x.x.x.x/path/to/media.amp", and it didn’t have any ideas ?

  PS : I’m using windows. Tried both CMD and PowerShell
