A lot of help

The last week has been unusually productive due to 3 people helping me with qtmux (well, everyday I get help from people at #gstreamer, but those 3 were directly helping).

In a non chronological order:

• Edward Hervey (bilboed at IRC) did some changes to faac plugin and now we can have qtmux muxing mov files that contain AAC which play at totem (gstreamer) and mplayer. (Quicktime Player still can't play those).
• Chris Cooksey is a possible future user of qtmux (one that really understands from the mov container) and while testing qtmux spotted 7 or 8 problems in the resulting files and reported me, so we fixed them (most related to timescale, dates and durations in the file).
• David Schleef (ds at IRC) sent me a patch for adding Dirac support into qtmux (it works!).
  

Thanks to you 3.

finally h264!

Just for letting you know: qtmux now supports h264 (and also a-law and mu-law)

Yay! \o/

Update on qtmux

I've been through the semester final exams the last weeks (my university timeline is all messed up) and time was short, so I couldn't update here with news on qtmux, but the semester in now finally over, so here are the new features:

• raw formats (both audio and video) and mp3 are working correctly in all players I tested (totem, vlc, mplayer and quicktime)
• support for h263 has been added and also works on the players above
• support for aac and amr has been added and it still doesn't work at quicktime, but works in totem and mplayer (vlc went nuts on my machine, and I still haven't got it to work again)
• ilst atom metadata support (used by itunes and qtdemux) has been added

I couldn't get aac and amr working, after some days searching for specs and testing applications that could generate qt files with amr or aac with no success, I noticed too much time was being lost and started working on other features.
None of the applications I tested could generate a qt file (with amr or aac) that quicktime would actually play, and I couldn't find any useful spec. I also tried inspecting bytes in some files that played successfully, but just looking at them wasn't enough, the different bytes are easy to find, but not easy to understand.

I said that I would add flavor selection in the previous post, but I was advised to work on some widely used formats first, so I did it.

GSoC is comming to an end in the next days, but work won't, qtmux has still a lot to be worked on and I'll keep it up.
