2017-02-04Fix dangerous castsAmaury Pouly2-4/+4
On Windows 64-bit, the size of long is 32-bit, thus any pointer to long cast is not valid. In any case, one should use intptr_t and ptrdiff_t when casting to integers. This commit attempts to fix all instances reported by GCC. When relevant, I replaced code by the macros PTR_ADD, ALIGN_UP from system.h Change-Id: I2273b0e8465d3c4689824717ed5afa5ed238a2dc
2017-01-15Fix codecs in simulator builds on WindowsAmaury Pouly3-2/+5
The mingw linker uses strlen() in some cases, and codeclib.c redefines it, that leads to mingw runtime init to call into our strlen() and then ci->strlen() which of course crashes. Apply the same fix as for malloc and friends: rename the symbol. The codeclib.h include is necessary for normal builds. Change-Id: Ifa85901a3e4a31cc0e10b4b905df348a239d5c99

In DEBUG build, the codec API struct is consider with DEBUG flag in apps/ but without DEBUG flah in rbcodecs/, leading to unmatched structure and horrible crashes in some cases (mostly encoders). I have no idea why the codecs Makefile removes the DEBUG flag (maybe for performance reasons?) but it cannot be right. Change-Id: Idb2c5f66741408ec2939624590fc39c4cf69fc2b
2016-09-07Opus: update resume offset correctly while playing.Adam Sampson1-0/+1
The codec wasn't calling ci->set_offset() while decoding; as a result, the saved offset in ci.id3->offset was only updated at the start of the file and when seeking. To reproduce the problem in the simulator or on a real device: - Start playing an Opus file. - Let it play until 15s, then turn the player off. - Turn back on and resume playback. This'll resume correctly from 15s (using time-based resume, I think, as the offset was 0?). - Let it play until 30s, then turn the player off again. - Turn back on and resume playback. This'll resume from 15s, based on the initial position from last time, when it should resume from 30s. I believe this will also fix FS#12799 ("Resuming opus file from bookmark is not working correctly"). Change-Id: Iba67368e0029c968ef802693767e0722719bc38b

2014-11-28Fix FS#13009.Michael Giacomelli2-5/+11
This file revealed several problems with our ASF parser: 1) The packet count in the ASF was actually a 64 bit value, leading to overflow in very long files. 2) Seeking blindly trusted the bitrate listed in the ASF header rather than computing it from the packet size and number of packets.

Sync to commit bb4b6885a139644cf3ac14e7deda9f633ec2d93c This brings in a bunch of optimizations to decode speed and memory usage. Allocations are switched from using the pseudostack to using the real stack. Enabled hacks to reduce stack usage.

2014-04-15libmad: Use 32bit unsigned for requantize table.Thomas Martitz1-2/+2
Implicit promotion of integer literals to unsigned long introduced a subtle bug on 64-bit systems due to weird sign extensions (leads to audible glitches in a few files). The table is originally designed for unsigned 32bit integers, and it works with those so use them. As a consequence the lookup table size is halved as well.

2014-03-10Implement time-based resume and playback start.Michael Sevakis36-192/+487
This complements offset-based resume and playback start funcionality. The implementation is global on both HWCODEC and SWCODEC. Basically, if either the specified elapsed or offset are non-zero, it indicates a mid-track resume. To resume by time only, set elapsed to nonzero and offset to zero. To resume by offset only, set offset to nonzero and elapsed to zero. Which one the codec uses and which has priority is up to the codec; however, using an elapsed time covers more cases: * Codecs not able to use an offset such as VGM or other atomic formats * Starting playback at a nonzero elapsed time from a source that contains no offset, such as a cuesheet The change re-versions pretty much everything from tagcache to nvram.

2013-11-18flac: fix seeking.Andrew Ryabinin1-1/+1
As comment in code states: "It is possible for our seek to land in the middle of audio data that looks exactly like a frame header from a future version of an encoder. When that happens, frame_sync() will return false. But there is a remote possibility that it is properly synced at such a "future-codec frame", so to make sure, we wait to see several "unparseable" errors in a row before bailing out." Currently we wait for 10 "unparseable" errors. libFLAC waits for 20. But I've got a valid flac+cue, wherein switching to certain track gave me 24 "unparsaeable" errors. Therefore I increased unparseable_count to 30.

2013-08-31Sync opus codec to upstream gitNils Wallménius115-4290/+4825
Sync opus codec to upstream commit 02fed471a4568852d6618e041c4f2af0d7730ee2 (August 30 2013) This brings in a lot of optimizations but also makes the diff between our codec and the upstream much smaller as most of our optimizations have been upstreamed or supeceded. Speedups across the board for CELT mode files: 64kbps 128kbps H300 9.82MHz 15.48MHz c200 4.86MHz 9.63MHz fuze v1 10.32MHz 15.92MHz For the silk mode test file (16kbps) arm targets get a speedup of about 2MHz while the H300 is 7.8MHz slower, likely because it's now using the pseudostack more rather than the real stack which is in iram. Patches to get around that are upcomming. Change-Id: Ifecf963e461c51ac42e09dac1e91bc4bc3b12fa3

For mp3_enc, split encoding duties between COP and CPU. For wavpack_enc, simply run the encoding on COP (splitting that one needs more consideration) which keeps the it and the UI from running on the same core. As a result, at least they are now useable on PP at "normal" sample rates. mp3_enc in all this gets an extensive renovation and some optimizations for speed, to reduce IRAM requirements and remove unneeded stuff.

2013-06-30Update software recording engine to latest codec interface.Michael Sevakis5-1224/+862
Basically, just give it a good rewrite. Software codec recording can be implemented in a more straightforward and simple manner and made more robust through the better codec control now available. Encoded audio buffer uses a packed format instead of fixed-size chunks and uses smaller data headers leading to more efficient usage. The greatest benefit is with a VBR format like wavpack which needs to request a maximum size but only actually ends up committing part of that request. No guard buffers are used for either PCM or encoded audio. PCM is read into the codec's provided buffer and mono conversion done at that time in the core if required. Any highly-specialized sample conversion is still done within the codec itself, such as 32-bit (wavpack) or interleaved mono (mp3). There is no longer a separate filename array. All metadata goes onto the main encoded audio buffer, eliminating any predermined file limit on the buffer as well as not wasting the space for unused path queue slots. The core and codec interface is less awkward and a bit more sensible. Some less useful interface features were removed. Threads are kept on narrow code paths ie. the audio thread never calls encoding functions and the codec thread never calls file functions as before. Codecs no longer call file functions directly. Writes are buffered in the core and data written to storage in larger chunks to speed up flushing of data. In fact, codecs are no longer aware of the stream being a file at all and have no access to the fd. SPDIF frequency detection no longer requires a restart of recording or plugging the source before entering the screen. It will poll for changes and update when stopped or prerecording (which does discard now-invalid prerecorded data). I've seen to it that writing a proper header on full disk works when the format makes it reasonably practical to do so. Other cases may have incorrect data sizes but sample info will be in tact. File left that way may play anyway. mp3_enc.codec acquires the ability to write 'Info' headers with LAME tags to make it gapless (bonus).
