# zmkv
Helper library for creating mkv files
Predefined A/V formats:
VP8,H264,OPUS,PCM,PCMA,PCMU,G729,SPEEX
Can be easily extended for any new format
# How to use
1. Library located in namespace ZMKV:
```cpp
using namespace ZMKV;
```
2. Create file writer, you can use default or make custom writer class derived from: MuxerIOWriterCallback
```cpp
MuxerIOWriterCallbackDefault muxerIOWriterCallbackDefault("./test.mkv");
```
3. Create muxer:
```cpp
Muxer muxer(muxerIOWriterCallbackDefault);
```
4. Create tracks:
```cpp
AudioCodecInfoACM audioCodecInfoACM(8000, 16, 1, ZMKV::wFormatTag::PCM);
AudioTrack audioTrack(muxer, audioCodecInfoACM, 0, 12345678);
VideoCodecInfoH264 videoCodecInfoH264(320,240);
videoCodecInfoH264.AddPPS(sps,sizeof(sps));
videoCodecInfoH264.AddPPS(pps,sizeof(pps));
VideoTrack videoTrack(muxer,videoCodecInfoH264,1,87654321);
```
5. Fill tracks:
```cpp
...
audioTrack.AddFrame(audioTimeStamp, 0, audio_buf, sizeof(audio_buf));
videoTrack.AddFrame(videoTimeStamp, isKeyFrame, video_buf, sizeof(video_buf));
...
```
6. Thats all!
