Socoder -> Handheld Coding -> Spinal Media Player

spinal	Here it is, the first 'proper' public test. Download Screenshot Currently you can only play output.smf in the player, but you can easily rename the files or whatever. The next proper release will have a file browser so you can play whatever you want. Also the converter uses a .ini file, so please look through it before running the damn thing. * note, you need ffmpeg installed to convert videos, there is a web address in the readme.txt for where to get the version I used, but any should do. I have already tested a few short clips and an entire movie with it, and it now works to my satisfaction, and yes, the converter is a bit on the ugly side, thats next on the list. any comments are of course welcome.

Thankyou. You can read about the Eponasoft Multimedia Codec at https://palib.info/forum/modules/newbb/viewtopic.php?&topic_id=3971 REQUIREMENTS: To convert movie files for viewing with 'Spinal Media Player', you will need ffmpeg, which you can get from - https://arrozcru.no-ip.org/ffmpeg_builds/ For easyest use, extract to the same folder as convert.exe (and convert.ini). Currently the converter does not create the framedump folder, so don't delete it. Spinal Media Player sould work on any homebrew compatable DS, remember to dldi patch. CONVERTER: The converter currently has no proper gui, it relys on the convert.ini file for collection the required data. This data includes the following - filename - Name (and full path) of the file to be converted. The input file can be any format that ffmpeg recognises (including dvd and youtube). aspect - The aspect ratio of the output file. This can be either 'full' or 'wide'. quality - The quality of the output file. Accepted values range between 1 and 31, 1 being best quality. However full screen movies should not be set lower than 6 or slowdown will occur. volume - The audio volume compared to the input file in percentage. 100 = same volume, 200 = double etc. output - Name (and full path) of the output file. THANKS: Eponasoft and Nicoco73 for comming up with the original idea and the code that smf is based on, Jayenkai, Dizi and anyone else who has helped with bug finding and advice as well as being pestered to test every single build and listen to me complaining cos I killed it again.

Jayenkai	At work.. I'll have a peek when I get back. But, great to see a release for the thing! -=-=- ''Load, Next List!''

spinal	One thing I am thinking about adding, is some sort of bookmark. There are plenty of times, when watching a movie on my DS (moonshell), I've wanted to switch the thing off and resume playback later, like on a lot of dvd players. -=-=- Check out my excellent homepage!

Jayenkai	I can't imagine that'd be too hard, since you already have the huge list of positions.. right? -=-=- ''Load, Next List!''

spinal	I noticed a syncing problem when playing Bill & Ted's Excellent Adventure encoded at quality 1, took too long to load the frames, so I recommend not encoding higher than about 4 in widescreen, not to mention at best quality, the thing was about 650mb. I think I'll try reducing the audio buffer size to hide any audio glitches a bit better to. -=-=- Check out my excellent homepage!

spinal	I was thinking of changing the movie format to have each frame referenced, rather than sized e.g. currently the format goes - Header Audio FrameSize FrameData FrameSize FrameData FrameSize FrameData FrameSize FrameData --v But I was thinking - Header Audio FrameLocation FrameLocation FrameLocation FrameLocation FrameData FrameData FrameData FrameData --v I figure a 3 hour movie is only going to use maybe 500kb if each reference is an int. This would enable me to use frame skipping rather than audio skipping. What do you guys think? -=-=- Check out my excellent homepage!

Jayenkai	What about cutting the audio into chunks, and placing chunks between the frames? Repetition might lead to a slightly bigger file format, but less jumping around would more than likely help things be a lot smoother. -=-=- ''Load, Next List!''

spinal	nah, tried that first. If the frame rate changes from the intended, the sound will leave gaps. I currently am trying to get rid of some clicking, not sure whats causing it, i think starting the sample is doing it \|edit\| I have managed to super-mega-drastically reduce the clicking, in fact I might have eliminated it completely, I can't tell if I'm imagining a clicking noise when its playing. As a consequence of the method I used, I seem to have the speed correct to, no noticeable recyncing going on yey!. For anyone who wants to know, I am using two buffers (or rather one buffer cut in half) offset so they slightly overlap, so just before the first buffer finishes, the second one starts so the playing is overlapped. I set palib to loop the sample, even though I am restarting it manually, I'm assuming this eliminates the clicking because the sound system is never actually stopped (again assuming that the clicking is caused by stopping the sample). Each buffer is just over half a second long. I think Jay suggested this method to me a long time ago, but I couldn't get it working at the time. So to some it up, I have a usable file format and a working player, I'm working on a file browser for it right this second. \|edit\| -=-=- Check out my excellent homepage!

ndstogo	Just a heads up.. the 080203 palib beta seems to be missing PA_PlaySoundEx2(). The sound implementation is "completely redone" to use Noda's ASLib: https://palib.info/forum/modules/newbb/viewtopic.php?topic_id=4195 Hope it helps! Nice work!!

spinal	I have not updated palib in ages, I have messed a lot with the arm7 code and I can't really remember what I have added. Upgrading would likely kill some of my old projects. -=-=- Check out my excellent homepage!

Jayenkai	Yeah, same here.. And not only my own tweaks, but through the past months since I first downloaded PALib and Devkit, loads of annoying incompatibilities seemed to creep in between the two. I've stuck with what actually works, because.. "It Just Works!" So, ok, maybe there's a few inconsistencies here or there. But my games run, and that's good enough for me. -=-=- ''Load, Next List!''

spinal	I'm going to byte the bullet and download the latest palib. I have backed up my old palib folder incase I need to re-add some of the arm7 code, so here goes... -=-=- Check out my excellent homepage!

Jayenkai	argh!
Sun, 02 Mar 2008, 12:09
spinal	Nope, going back, killed everything, even 'make'. Guess I'm not using amr7 side mp3 for movie player -=-=- Check out my excellent homepage!
Sun, 02 Mar 2008, 14:53
Jayenkai	lol! Yup, just stick to what works.
Sun, 02 Mar 2008, 23:15
spinal	Well, initial tests look good for the new format. We'll see how bad it gets when I add sounds and other options. -=-=- Check out my excellent homepage!
