[Laszlo-dev] media formats supported by SOLO (swf 7 / 8) ?

[Cortlandt Winters]

Hi Guys,

I haven't tested this in laszlo, but the player is supposed to support this
at least as of flash player7, since the player just recently bumped up from
5 to support 6,7 and 8 output I wouldn't be surprised if there was a bug
mismarking the tag of a newly accepted type of sound with that of an older
format or a streaming sound as an event sound. If so, that might be easily
fixed and may be worth checking for.

The swf7 file format documentation describes the player accepting sample
rates of 5512Hz, 11025Hz, 22050Hz and 44100Hz in both stereo and mono.

(pseudo quoted)
The DefineSound tag defines event sounds and includes the sampling rate,
size of each sample( 8 or 16 bit) a flag for stereo or mono and an array of
audio samples. The data is flagged with 0 or 3 for uncompressed raw samples,
1 if compressed with adpcm, 2 if compressed with mp3  in swf4+ and 6 if with
Nellymosser asao in swf6+

Streaming sounds are different and have a SoundStreamHead or
SoundStreamHead2 tag before the first data block.Then there are a series of
subdivided frames for the streaming sounds like with mp3, it may be that
you're mp3 is being tagged as an event sound.

http://www.notebookmargins.com/ref/flash_file_format_specification.pdf has
the details around page 148 with the details of mp3 compression on 151

HTH

I've been quiet lately but I'm trying to keep up with all the changes. I
Love the work you guys are continuing to do.
