Define feature test macros in common.h This enables necessary functions once for all. As a consequence, define common.h before any other header. 2021-01-09 02:24:51 +08:00			`#include "common.h"`

Replace SDL types by C99 standard types Scrcpy is a C11 project. Use the C99 standard types instead of the SDL-specific types: SDL_bool -> bool SintXX -> intXX_t UintXX -> uintXX_t 2019-03-03 06:52:22 +08:00			`#include <stdbool.h>`

Extract current video_buffer to frame_buffer The current video buffer only stores one pending frame. In order to add a new buffering feature, move this part to a separate "frame buffer". Keep the video_buffer, which currently delegates all its calls to the frame_buffer. 2021-07-04 18:39:03 +08:00			`#include "frame_buffer.h"`
Make SKIP_FRAMES a compilation flag The skip_frames flag was a non-configurable runtime flag. Since it is not exposed to the user, there is no need for a (possible) runtime cost. For testing purpose, we still want it to be configurable, so make it a compilation flag. 2018-02-07 19:25:52 +08:00

Update code style Limit source code to 80 chars, and declare functions return type and modifiers on a separate line. This allows to avoid very long lines, and all function names are aligned. (We do this on VLC, and I like it.) 2019-03-03 03:09:56 +08:00

Make video_buffer more generic The video buffer took ownership of the producer frame (so that it could swap frames quickly). In order to support multiple sinks plugged to the decoder, the decoded frame must not be consumed by the display video buffer. Therefore, move the producer and consumer frames out of the video buffer, and use FFmpeg AVFrame refcounting to share ownership while avoiding copies. 2021-04-11 21:01:05 +08:00			`bool`

Move frame swapping logic to frame.c Expose frames_offer_decoded_frame() and frames_consume_rendered_frame() so that callers are not exposed to frame swapping (between the decoding and rendering frames) details. 2018-02-09 02:23:24 +08:00
