MPWebServices and FFmpeg (1 Viewer)

[cheezey]

Has anyone succeeded in using ffmpeg with MPWebServices?

If so can you share the config.xml you used.

I have tried many args & combinations of input/output methods but always get one of:

• Invalid option.
• Pipe Stream isn't ready.
• Cannot process request because the process (nnnn) has exited.

Hey Cheezey

I had the same issues as you and never figured out what the problem was, I would also occasionally have the same problem with Mencoder. First I thought FFmpeg didn't like async read/writes as it worked perfect every time when I created another thread to handle the input and did all read/writes synchronously.

However I have since written my own streamer that is fully async, using only 1 thread, and it works OK. The encoding parameters, etc are all hardcoded so the EncoderWrapper/Config classes are not used, I also only pipe via ffmpeg's std in/out so no named pipes.

So in theory it should work, the problem lies somewhere within the encoder wrapper I think.
Attached is my streamer that successfully outputs flash video using ffmpeg (to enable viewing on an embedded player)

Hope it helps

**EDIT**

Just checked, my code isn't truly async as the Reads are synchronous so maybe the prob is with ffmpeg and async reads
