obs-ffmpeg: Rename obs-ffmpeg-aac.c file Renames obs-ffmpeg-aac.c to obs-ffmpeg-audio-encoders.c due to the fact that it can be abstracted for multiple audio encoders. 2017-07-31 14:29:50 -07:00			`obs-ffmpeg-audio-encoders.c`

obs-ffmpeg: Add ffmpeg muxer In addition to the flv file format, this allows the ability to save to container formats such as mp4, ts, mkv, and any other containers that support the current codecs being used. It pipes the encoded data to the ffmpeg-mux process, which then safely muxes the file from the encoded data. If the main program unexpectedly terminates, the ffmpeg-mux piped program will safely close the file and write trailer data, preventing file corruption. 2015-05-28 23:11:37 -07:00			`obs-ffmpeg-mux.c`

obs-ffmpeg: Add texture-based NVENC encoder implementation Adds a texture-based NVENC implementation which passes OBS NV12 output textures directly to NVENC without downloading them off of the GPU, increasing NVENC performance by a significant margin.

Revamp API and start using doxygen The API used to be designed in such a way to where it would expect exports for each individual source/output/encoder/etc. You would export functions for each and it would automatically load those functions based on a specific naming scheme from the module. The idea behind this was that I wanted to limit the usage of structures in the API so only functions could be used. It was an interesting idea in theory, but this idea turned out to be flawed in a number of ways: 1.) Requiring exports to create sources/outputs/encoders/etc meant that you could not create them by any other means, which meant that things like faruton's .net plugin would become difficult. 2.) Export function declarations could not be checked, therefore if you created a function with the wrong parameters and parameter types, the compiler wouldn't know how to check for that. 3.) Required overly complex load functions in libobs just to handle it. It makes much more sense to just have a load function that you call manually. Complexity is the bane of all good programs. 4.) It required that you have functions of specific names, which looked and felt somewhat unsightly. So, to fix these issues, I replaced it with a more commonly used API scheme, seen commonly in places like kernels and typical C libraries with abstraction. You simply create a structure that contains the callback definitions, and you pass it to a function to register that definition (such as obs_register_source), which you call in the obs_module_load of the module. It will also automatically check the structure size and ensure that it only loads the required values if the structure happened to add new values in an API change. The "main" source file for each module must include obs-module.h, and must use OBS_DECLARE_MODULE() within that source file. Also, started writing some doxygen documentation in to the main library headers. Will add more detailed documentation as I go. 2014-02-12 07:04:50 -08:00			`${obs-ffmpeg_SOURCES})`
