I am using Camtasia on my Mac and I need to export swf. For now, I am trying to export MP4 and then convert it to swf, but file size gets enormous. Is there a shorter and efficient way to produce swf on Mac?
First you will have to get a .swf converter then you would have to make Camtasia transfer into whatever file the .swf converter can convert.

I am trying to build a one to many video publish application based on webrtc and installed licode to my server.
My question is,
Is there any way export frames to a specific folder as jpg, png etc.
don't think they are proving that option yet, but a workaround can be: record the video stream on the server, extract the frames from the recorded file using ffmpeg
I've been searching for this for a few days now, but nothing seems to quite answer or work for me, so please forgive me if I'm asking a stupid question or one that seems to have been answered elsewhere.
I have an AVI file encoded using the GMP4 video codec, currently installed on my computer so I can PLAY the file in Windows Media Player for instance. What I'm trying to do is open/decode the file for editing purposes, in order to be able to stitch two video files together. I do not require it to be output in the same format, but rather only opened for editing, get the frames and then I can output to a more standard format.
The problem I'm getting is that there is no DirectShow filter created for this format, so it won't open using that for me (haven't worked too deeply into it, but all samples fail to load the video file). FFMPEG tries to read the file, states that the header is incorrect but it'll attempt to read it anyway, then dies stating that I need the GMP4 codec. As I'd stated earlier, I have the particular codec installed but FFMPEG doesn't seem to notice or have access to it.
Is there anything that will allow me to use the system-installed codecs to decode the video frames? It seems strange to me that Windows Media Player can do something, but I can't programatically repeat it. I'm not restricted to C++ or C#, though C# would definitely be a preferred language.
Thanks All,

I spent all day with the same problem. Solution is to install AVISynth, and then you can load with ffmpeg any AVI file for whom the system has a VfW codec. Instead of passing ffmpeg your AVI input file, create an .avs file with a single line containing AviSource("your-avi-filename") and passing ffmpeg the .avs filename.
Suppose you want to convert your input.avi in a proprietary video CODEC into an h263 format (supposing your input.avi has a supported h263 frame size):
echo AviSource("input.avi") > input.avs
ffmpeg -i inputs.avs -vcodec h263 output.avi
Nuno has a great answer, but you want to avoid command line converts, you can use the AForge.Net c# library to access AfW codecs, FFMpeg codecs or even DShow codecs (some CCTV DVRs do encode in DShow).
There is also a way to open Windows Media Player as a c# object and grab frames from it. Email me if you want more information - it sounds like we're working on similar projects.
I have a college project and I have a presentation almost done using adobe captivate. It saved as a .cptx file. My lecturer left a message online saying that it has to be an .swf file. There is no option on captivate to convert it to an .swf. When I export it to flash and play it, it is completely blank and none of my work appears.
Any ideas as to how I can convert my .cptx to .swf? (With the presentation coming out as it did on captivate)
Thanks.
To convert a cptx file to a SWF you need to 'publish' your project. Go to File > Publish and choose the SWF option (this may be different depending on which version of Captivate you're using).
Hope this helps.

I understand that the SpeechSynthesizer (System.Speech.dll) can be used to convert text to speech. I am working on an application that requires the ability of saving the text as mp3 and wav file.
Is this possible using WPF?
I believe that you should be easily able to save to a WAV file via SpeechSynthesizer::SetOutputToWaveFile. I don't think there is built-in support in .NET for converting to MP3, but this should be straightforward with the help of a 3rd party library/utility (like LAME) once you have the audio data as WAV.
Has anyone found a way to save a FlowDocument as BAML or other compressed format? I can import XML with images to create a new FlowDocument:
<TextRange class instance>.Load(fs, DataFormats.Rtf)
However, I haven't found a good way to save it in a 'native' compressed format. Uncompressed XAML is easy to generate using:
<TextRange class instance>.Save(fs, DataFormats.Xaml);
But is there any programmatic method to save it to a compressed format?
If there isn't an existing method, does anyone know where to find a programmatic XAML compiler? Or even just the BAML specifications? I could programmatically generate an entire XAML window with the FlowDocument embedded, but I'd still want to convert the XAML to BAML for faster load times. I'm using relatively large rtf documents and conversion time using DataFormats.Rtf is significant.
I do not think it is possible... The BamlWriter is marked as internal, this will hopefully open up soon!
I unfortunatly do not know of any XAML compilers
Well, it turns out you can run Visual C# 2008 Express w/o the GUI. And you can modify the final program name via code before you compile as well. I'm sure you can do it via APIs, but here's the hack I found:
The program's is name determined in .csproj, in the xml tag.
Run via code or batch file: "\Common7\IDE\vcsexpress" ".sln" /rebuild Release /projectconfig Release /out errors.txt
I like to examine and then delete the errors.txt after each run to make it easier to see if I got a clean build. This isn't ideal because you have to have a full bought version of Visual C# 2008 on each machine you use this way, but it is a way to create a new executable to display each flow document in a programatic way. Also if you have an error in your XAML, you may generate a program that won't run.
Note that the BAML format does NOT compress the text, only the tags and other 'plumbing'. Even the Margin and Padding information is saved in clear ASCII. This is inherited by the end .exe leaving the text clearly visible in sections to notepad or similar.
The XamlPackage format is compressed:
<TextRange class instance>.Save(fs, DataFormats.Xaml);
