• Museum of Multimedia Software, Part 2

  16 août 2010, par Multimedia Mike — Software Museum

  This installment includes a bunch of old, discontinued Adobe software as well as some Flash-related mutlimedia software.

  Screen Time for Flash Screen Saver Factory
  "Create High Impact Screen Savers Using Macromedia Flash."

  
  
  

  Requirements include Windows 3.1, 95 or NT 3.5.1. A 486 computer is required to play the resulting screensavers which are Flash projectors using Macromedia Flash 3.0.

  Monster Interactive Instant GUI 2
  Create eye-popping GUIs more easily for use in Flash. Usability experts would argue that this is not a good thing.

  
  
  

  Adobe Dimensions 3.0
  "The Easy Yet Powerful 3D Rendering Tool." This software was end-of-life’d in late 2004-early 2005 (depending on region).

  
  
  

  Adobe ImageStyler
  "Instantly add style to your Web site." Wikipedia claims that this product was sold from 1998 to 2000 when it was superseded by Adobe LiveMotion (see below).

  
  
  

  Google is able to excavate a link to the Latin American site for Adobe ImageStyler, a page that doesn’t seem to be replicated in any other language.

  Adobe LiveMotion
  "Professional Web graphics and animation." This is version 1, where the last version was #2, released in 2002.

  
  
  

  Adobe Streamline 4.0
  "The most powerful way to convert images into line art." This was discontinued in mid-2005.

  
  
  

  Adobe SuperATM
  "The magic that maintains the look of your documents." This is the oldest item in my collection. A close examination of the back of the box reveals an old Adobe logo. The latest copyright date on the box is 1992.

  
  
  

• FFmpeg/MP4 - Force all existing frames to play at fixed frame rate

  16 mai 2020, par MJoseph

  I have an MP4 video file that I suspect is corrupt, in that mediainfo reports a variable frame rate, but I believe the frames present are meant to be played at a fixed frame rate. This discrepancy causes video stuttering. Is there any way to force an MP4 container (by editing header info, or frame timing tables) to simply play back all existing frames at a fixed frame rate (i.e. 24fps). Every tip I've read assumes you want to drop and/or add frames to achieve a new frame rate, while keeping all the old frame timings (i.e. ffmpeg -r or ffmpeg -filter). These methods end up preserving the stutter and altering the size of the file. I would like to throw out the frame timings, but keep all frames, and just play them back at a constant rate. Is this possible ?

  


• How to convert MPEG2-TTS to MPEG2-TS format to playback using ffplay

  29 février 2024, par Asustor

  I know some OSS such as ffmpeg or gstreamer don't support to play-back MPEG2-TTS stream.
Then, I tried to convert 192 bytes TTS packet to 188 bytes TS packet by deleting first 4 bytes like :

  


  def conv_tts2ts(rtp_payload):

    payload_len = len(rtp_payload)
    if payload_len % 192 != 0:
        raise

    pkt_num = int(payload_len / 192)
    ts_data = bytearray()
    for i in range(pkt_num):
        spos = 192 * i
        epos = spos + 192
        tmp = rtp_payload[spos:epos]
        ts_data.extend(tmp[4:])

    return ts_data

# after this, send ts_data with RTP header received from MPEG2-TTS streamer via UDP/IP.



  


  However, ffplay and ffprobe don't reaction.

  


  I expect to be able to play-back using ffplay as MPEG2-TS format.
Please tell me how to convert TTS to TS in order to deocde by ffmpeg ?
