Podcast Producer 2 REST api
11 septembre 2009I’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

Pass camera input to ffmpeg
30 mai 2017, par Sachin SononeI am trying to develop an delphi app which will show a preview of the camera in the delphi form and then send the frames of video as images to the ffmpeg in the stdin of ffmpeg. ffmpeg then broadcast the video to wowza server over rtmp. but fmpeg gives an error ’pipe:0 Bad file descriptor’
FFMPEG command:
ffmpeg -f image2pipe -i pipe:0 -c:v libx264 -y -report -f flv wowza_urlI followed this https://msdn.microsoft.com/en-us/library/ms682499(VS.85).aspx article to build the parent app which will open ffmpeg as a child and use FFmpeg’s stdin to pass input
// Create a pipe for the child process's STDOUT.
Createpipe(STDOut_ReadPipe, STDOut_WritePipe, @Security,0);
// Ensure the read handle to the pipe for STDOUT is not inherited.
SetHandleInformation(STDOut_ReadPipe,HANDLE_FLAG_INHERIT,0);
// Create a pipe for the child process's STDIN.
if ( CreatePipe(STDIn_ReadPipe , STDIn_WritePipe, @Security, 0) = true) then
// Ensure the write handle to the pipe for STDIN is not inherited.
SetHandleInformation(STDIn_WritePipe, HANDLE_FLAG_INHERIT, 0) ;This the code to start ffmpeg process
FillChar(StartupInfo,Sizeof(StartupInfo),0);

S := args;
UniqueString(S);
StartupInfo.hStdError := STDOut_WritePipe;

FFMPEG and MSA1 Codec Issues when Converting WMV to MP4 Video
30 décembre 2023, par user136819I 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 ! :)
