Rockbox mail archiveSubject: Adding RM support - Weekly updateAdding RM support - Weekly update
From: Mohamed Tarek <mtarek16_at_gmail.com>
Date: Sun, 9 Aug 2009 11:36:31 +0300 Greetings everyone. Last week, support for AC3 audio in RM container was added successfully. Just after committing the code I discovered two bugs; seeking was a bit choppy - like if you seek to 4:24 for example, playback starts from 4:21 or 4:28, i.e not the exact desired seek time. Also, I always got segfaults at the end of the track. But those two bugs were fixed. So now, rockbox supports RM playback with the following codecs : - Cook - AAC - AC3 All three codecs support seeking as well. Next I'll start working on ATRAC. This codec isn't supported by rockbox, neither does it have fixed point implementations (or I haven't yet discovered any!), so supporting this codec will take a long time - even beyond the end of gsoc - that's why I left it till the end. Porting this codec should go through the following steps : - Isolation of the codec from libffmpeg. - Incorporating the codec in the current test program, and be able to convert atrac audio in rm container to wav. - Converting the codec to use fixed point math - this is where I believe I'll spend the most time. - Porting the codec to rockbox. That's all for now. Cheers, MT Received on 2009-08-09 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
