) |
Create a WebMClusterParser from given parameters.
timecode_scale | indicates timecode scale for the clusters. |
audio_stream_info | references audio stream information. It will be NULL if there are no audio tracks available. |
video_stream_info | references video stream information. It will be NULL if there are no video tracks available. |
vp_config | references vp configuration record. Only useful for video. |
audio_default_duration | indicates default duration for audio samples. |
video_default_duration | indicates default duration for video samples. |
text_tracks | contains text track information. |
ignored_tracks | contains a list of ignored track ids. |
audio_encryption_key_id | indicates the encryption key id for audio samples if there is an audio stream and the audio stream is encrypted. It is empty otherwise. |
video_encryption_key_id | indicates the encryption key id for video samples if there is a video stream and the video stream is encrypted. It is empty otherwise. |
new_sample_cb | is the callback to emit new samples. |
init_cb | is the callback to initialize streams. |
decryption_key_source | points to a decryption key source to fetch decryption keys. Should not be NULL if the tracks are encrypted. |
