• My Website Downloads MP4s Instead of Plays them

  18 juillet 2014, par user3412869

  I have a website I am working on and I have an uploads/ folder with mp4 files. When I test this site locally using XAMPP and click the link to the MP4 files, Chrome plays the MP4 with the browser and then when I click the back button it takes me back to my site. When I upload all of the site files to a webserver and click the same links to view the mp4 files it downloads the files and keeps me on the same page. However, I would like it to perform the same actions it does when I am developing locally, and play them, not download the files.

  Is it possible to have Chrome play Mp4 files that are hosted on a server and not download them ?

• 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"

• An ISO ripped from a DVD-Video is empty but still plays in Apple DVD-Player ?

  7 avril 2015, par IAmDamoSuzuki

  I’ve run across a number of DVDs that seem to contain no visible data. The ISOs that I rip from them (using ddrescue) contain no VIDEO_TS folders, or any folders at all. However, if I use df on the mounted filesystem it claims to have a size.

  Even stranger however, is that the Apple DVD-Player and MPEG-Streamclip will still open and play the DVD. I’m unable to process the ISOs using ffmpeg because terminal can’t see any files !

  Has anybody experienced something like this before ?
