"Why isn't the multiplexed encoded data from Google Chrome's WebCodecs AVC Encoder displaying properly?"

Multiplexed encoded data from Google Chrome's WebCodecs AVC Encoder is not displaying properly

There could be several reasons why the multiplexed encoded data from Google Chrome's WebCodecs AVC Encoder isn't displaying properly:

Codec Differences: Google Chrome uses the OpenH264 codec, which might handle encoding frames differently compared to other encoders. This can lead to variations in output quality or compatibility1.

MP4 File Structure: Issues with the MP4 file structure, particularly the MDAT box (which contains the actual media data), can cause display problems. Ensure that the MP4 file is correctly structured1.

Configuration Settings: Incorrect configuration settings, such as bitrate, codec type, or frame rate, can affect the quality of the encoded video. Double-check your encoder configuration to ensure it's set up correctly2.

Browser Compatibility: Different browsers may handle WebCodecs differently. Testing the encoded video in multiple browsers can help identify if the issue is browser-specific.

Frame Data Processing: Ensure that the input data is correctly converted and processed before encoding. Consistent input conversion techniques can help mitigate issues1.

Potential Solutions: Cross-Verification: Use tools like MP4Box to break down the MP4 file into its constituent atoms and verify any anomalies.

Switch Encoders: If feasible, experiment with different encoders that have consistent support across browsers.

Debugging: Review the output from different browsers side-by-side and scrutinize the hexadecimal data to identify inconsistencies.

By addressing these potential issues, you should be able to resolve the display problems with the multiplexed encoded data from Google Chrome's WebCodecs AVC Encoder.
