Re: noise added on OGG playback: msg#00214python.pygame
> Standard WAV files should be supported, but only uncompressed raw files. > Like AVI, there are a ton of codecs that can be used inside a WAV. I am getting the following result: the file plays from zero, but returns the following error when asked to play from 4.3 (seconds): "pygame.error: Position not implemented for music type". This happens if I (a) just use the original 16/44.1 WAV that I rendered from my sequencer, (b) convert to WAV (signed 16-bit PCM) in Audacity, or (c) convert to AIFF (signed 16-bit PCM). The other codecs given as options will result in files that pygame cannot open. So I also found out that an OGG rendered from a 24-bit WAV file behaves the exact same way as my OGG rendered from the 16-bit file. I do think that there is a bug in SDL_mixer, or maybe the way Pygame combines SDL's Mix_SetMusicPosition and Mix_PlayMusic (??). I'll look into SDL stuff--it would be great if I could get into the SDL_mixer internals, because I'm motivated with some ideas even though I'm pretty new to programming and DSP. Thanks for the responses. -david. |
