• Can't obtain information with ffmpeg to Smooth Streaming Manifest file

  4 mars 2015, par Alberto

  I’m trying to get details for a stream of protocol Microsoft Smooth Streaming, with ffmpeg tools (ffprobe and ffplay) but when I run the next command :

  ffprobe -i http://b31282.cdn.telefonica.com/31282/Manifest

  I obtain this :

  http://b31282.cdn.telefonica.com/31282/Manifest: Invalid data found when processing input

  I assume that this Manifest file is correct and complies with standards of Smooth Streaming . This is a brief extract of Manifest file :

  <smoothstreamingmedia majorversion="2" minorversion="0" duration="0" timescale="10000000" islive="TRUE" lookaheadfragmentcount="2" dvrwindowlength="6000000000" canseek="TRUE" canpause="TRUE">

    <streamindex type="audio" language="esp" subtype="" chunks="0" timescale="10000000" url="QualityLevels({bitrate})/Fragments(audio_esp={start time})"></streamindex>
  
    <streamindex type="video" language="" subtype="" chunks="0" timescale="10000000" url="QualityLevels({bitrate})/Fragments(video={start time})"></streamindex>
  
  </smoothstreamingmedia>

  Is a Fedora 21 and ffmpeg version and configuration is :

  ffmpeg version git-2015-02-27-d490b26

• FFMPEG and MSA1 Codec Issues when Converting WMV to MP4 Video

  30 décembre 2023, par user136819

  I have a WMV video file (around 60 MB size, 01:23:00 length) and I'm running a Windows Server 2016 64-bit machine for testing.
  
As far as I know, this video file was recorded using Microsoft Live Meeting 2007 back in April 2010 and there is also an associated audio file (which I'm able to play).

  


  I tried to play the video file on my machine using VLC player (latest update), however, I always see this weird MSA1 codec error :

  


  

  


  So I tried to resolve this problem by downloading and installing the Combined-Community-Codec-Pack-64bit-2015-10-18, and using its MPC-HC 64-bit player to play the video...
I still couldn't get it to play ! Here are the logs shown by the MPC player :

  Since that didn't work, I tried installing the Microsoft MPEG-4 V1/2/3 VKI Codec for ASF files and still couldn't get the players to play the video and saw the same errors as above !

  


  As a final attempt, I tried to convert this video to MP4 format using FFMPEG (version from 2020). Even this failed. Here are the logs :

  I wish to know, is there any other way I can convert this video to a more modern format so that I can play it on a modern machine and modern video player ?
  
What other codecs am I missing here ? (if so, where can I get them ?)
  
FYI, as mentioned earlier at the top, I'm only able to play the associated audio file...

  


  I'm fairly new to all this stuff, so any help is appreciated.

  


  Thanks in advance ! :)

  


• Podcast Producer 2 REST api

  11 septembre 2009

  I’ve been working on documenting the REST api that PCP2 uses for client server communication as part of a new project. I thought it might be useful to other folks. Consider this a work in progress - I’ve only documented the workflow for doing a multisource recording so far. Follow the job for the info.

  Each section gives a sample command and a sample response.

  All pages are behind basic HTTP auth.

  General sequence of events

  * get workflow list
  * get cameras
  * request status for camera (including thumbnail)
  * start cameras
  * create recording enclosure
  * stop cameras, provide submission_UUID returned by above step, include title
