harmony 鸿蒙FAQs About Transcoding
FAQs About Transcoding
Why does the audio encoding format change when the application sends a video for transcoding?
If the audio track format is not specified during transcoding, the system converts it to AAC by default.
What should I do if the transcoding capabilities provided by the system fail to be called?
- Check whether the current transcoding system supports the video and the target video format settings.
For details about the transcoding capabilities, see AVTranscoder and AVCodec Supported Formats.
- When receiving an error event, the application should send the source video. When receiving a complete event, the application first call release before performing operations such as sending or uploading the transcoded video.
