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

*URL : https://pcpserver:8170/podcastproducer/info

*Type : GET

Resurrecting SCD

6 août 2010, par Multimedia Mike — Reverse Engineering
When I became interested in reverse engineering all the way back in 2000, the first Win32 disassembler I stumbled across was simply called "Win32 Program Disassembler" authored by one Sang Cho. I took to calling it ’scd’ for Sang Cho’s Disassembler. The original program versions and source code are still available for download. I remember being able to compile v0.23 of the source code with gcc under Unix ; 0.25 is no go due to extensive reliance on the Win32 development environment.

I recently wanted to use scd again but had some trouble compiling. As was the case the first time I tried compiling the source code a decade ago, it’s necessary to transform line endings from DOS -> Unix using ’dos2unix’ (I see that this has been renamed to/replaced by ’fromdos’ on Ubuntu).

Beyond this, it seems that there are some C constructs that used to be valid but are now rejected by gcc. The first looks like this :

PLAIN TEXT
C :
return (int) c = *(PBYTE)((int)lpFile + vCodeOffset) ;
Ahem, "error : lvalue required as left operand of assignment". Removing the "(int)" before the ’c’ makes the problem go away. It’s a strange way to write a return statement in general. However, ’c’ is a global variable that is apparently part of some YACC/BISON-type output.

The second issue is when a case-switch block has a default label but with no code inside. Current gcc doesn’t like that. It’s necessary to at least provide a break statement after the default label.

Finally, the program turns out to not be 64-bit safe. It is necessary to compile it in 32-bit mode (compile and link with the ’-m32’ flag or build on a 32-bit system). The static 32-bit binary should run fine under a 64-bit kernel.

Alternatively : What are some other Win32 disassemblers that work under Linux ?

Error in converting audio file format from ogg to wav [on hold]

9 juin 2014, par Sumit Bisht

I am trying to convert an ogg format file that was created using webrtc (html5 usermedia content generated on firefox) and transferred and decoded on the server into a wav file through ffmpeg but am getting this error on cmmand line while trying to convert :

$ ffmpeg -i 2014-6-5_16-17-54.ogg res1.wav

Error opening filters!

Although, I am able to play the file on server and using the same command, am able to convert .ogg files generated somewhere else. What might be I missing ?

Edit :
Here’s the source code that is used to write to the file :

1) During startup - use the methods of getUserMedia API.

navigator.getUserMedia({

        audio: true,

        video: false

    }, function(stream) {

        audioStream = RecordRTC(stream, {

            bufferSize: 16384

        });

        audioStream.startRecording();

2) During stopping of the recording - extracting the recorded information.

function(audioDataURL) {

     var audioFile = {};

     audioFile = {

       contents: audioDataURL

     **strong text**};

On server end, the following code is creating a file from this data :

dataURL = dataURL.split(',').pop(); // dataURL is the audioDataURL as defined above

fileBuffer = new Buffer(dataURL, 'base64');

fs.writeFileSync(filePath, fileBuffer);
