[FFmpeg-devel] AMR file seeking and total playtime

Hi ffmpeg Developers,

I wrote a letter to VLC developers:

I prefer to use VLC everywhere if it is possible. I really love it.

I advised to my project leader to use VLC instead of Quicktime for AMR
playback in Windows environment, because it is possible to play AMR
files in VLC too. However I found few features lack:

* seeking in AMR file is not possible,
* VLC unable to display total time of AMR files,
* No plugin to play AMR files in Internet Exporer and Firefox. (Or is it
possible in another way?)

I hope it is possible to implement, fix the challenges I described
above. If we could replace Quicktime as AMR player in our web based
application I am sure I can offer monetary donation to create such
possibilities. Who is responsible for AMR playback capabilities, and
plugin module for browser? What is the best way to achieve our goals?
What deadline for working beta can we set?

They asked me to write a letter to ffmpeg developers. So what I want is
to support VLC described above. Can you implement such AMR related
improvements in ffmpeg? If we can achieve our goals I am sure our
company will donate the development.  What is your opinion?

Thank you in advance!

Best regards,
