fd3865a8e6 Detecting default sample rate of default audio device (Windows seems to play audio out of sync on certain audio drivers, if there is a mismatch between OpenShot and the default system audio sample rate). This info will help debug issues. Adding back in a mutex on Timeline::GetFrame causing crashes. 2022-02-11 14:12:25 -06:00

133bae40c3 Adding pre-roll to VideoCacheThread, and making video & audio threads wait for the isReady() method before playing. Also fixed an audio bug where our internal buffer was not being cleared on seek. Removed some unused caching from Clip, and did some minor refactor on FrameMapper/Clip cache clearing. 2022-01-26 17:56:33 -06:00

59138ea3e4 Adopt license management via Reuse project/tool (#711) 
* reuse-managed license/copyright headers

reuse is a tool for compliance with the REUSE recommendations. See
<https://reuse.software/> for more information, and
<https://reuse.readthedocs.io/> for the online documentation.

* Set jsoncpp license
* Add MIT license for Decklink sources
* Explicitly license examples/
  - Add headers to source files
  - Change blanket licensing in .reuse/dep5 to only cover binary media
  - Import CC-BY-3.0 license and assign to sintel_trailer

6aab6fd957 Audio: New device name lookup 
- A new AudioDevices class replaces the AudioDeviceInfo struct.
  It has a single method, getNames(), which:
  * creates an AudioDeviceManager (NOT using the singleton)
  * scans for available devices
  * returns the results as a std::vector containing
    std::pair<std::string, std::string> objects

  (The AudioDevices device manager is never initialize()d, so
  no devices are opened; it should be safe to use even DURING
  playback, without disruption.)

  By using STL containers (rather than a custom struct) to return
  the results, Python is able to consume the output as a native
  list of tuples.

  AudioDeviceInfo is still present for compatibility, but deprecated.

- Eliminated some unnecessary conversions (like):
  * calls to std::string::c_str, when passing to juce::String.
    juce::String accepts std::string directly.
  * calls to juce::String::toRawUTF8, when creating std::string.
    There's a juce::String::ToStdString, which is better.

0c4e1bcce4 Improving performance after working with google-prof, to profile CPU. Calling OMP_MP_NUM_PROCESSORS less often, since it's quite expensive according to profiling. Adjusting Timeline final_cache to match the video caching thread max_frames, so one doesn't clobber the other. Also, fixing an issue with openshot-player, where a video file with no audio skips horribly. 2021-02-04 17:28:07 -06:00

140fbaddff Added new AudioDeviceInfo struct, and populate a vector of them on QtPlayer initialization. This allows a user to overwrite the preferred audio device by using the setting PLAYBACK_AUDIO_DEVICE_NAME. 2019-04-23 16:45:02 -05:00

9dbb063ded Persist any error returned by JUCE during initialise() method, such as sample rate issues on Windows (when playback and recording sample rates do not match, which breaks WASAPI) 2019-04-04 00:55:47 -05:00

c95db460d6 Big update! Updating all "long int" frame number types to int64_t, so all 3 OSes will produce the same depth and precision on frame numbers. Also removing variable bitrate support temporarily, since it causes more problems than it solves. 2017-09-28 16:03:01 -05:00

b3ca56b5ab Another attempted fix for audio device management. Moving CloseAudioDevice() call to only invoke when quiting OpenShot, and only initializing the JUCE audio manager 1 time. This fixes a audio freeze in Windows when the preview window launches. 2017-03-26 23:51:03 -07:00

85ac4bf6d2 Updating references to frame number / position to long int, there were still quite a few old "int" declarations, which limits the length of frame number. Also, updated precision of KeyFrames to use double (instead of float) for higher precision, which fixed lots of issues with very long videos (since our FrameMapper used a KeyFrame object to create a map to new frames) 2017-01-24 18:39:17 -06:00

98ccfb5ee1 Fixing cmake build scripts to support 64bit on Windows. Also refactoring some pointer handling to support 64bit on Windows (Linux and Mac have always supported it). Adding instructions for setting up a Windows 64 bit build environment using MSYS2. 2016-08-12 19:15:19 -05:00

92a9db2aa3 Improved detection of missing audio frames, and missing video frames. Also improved logic for giving up on missing frames in general. Also removed some deadlocks related to Seeking (Close() and Open() were deadlocking). The end result is much improved compatability with reading video files. 2016-06-29 02:42:00 -05:00

179d091005 Moved AppendDebugMessage to ZmqLogger, and updated 100+ references to use this new function. Removed debug var from readers/writers, and moved it to ZmqLogger.Enable(true/false). This allows debug output from all classes and functions, without any duplicate code. Also added some additional debug output for video playback and audio readers. 2016-04-21 01:39:17 -05:00
