The "Resource temporarily unavailable" error message in avcodec_receive_frame typically indicates that the function is unable to retrieve a decoded frame from the codec at the current time.
There are several potential reasons why this error may be occurring, including:
1. Insufficient resources: If your system is low on memory or processing power, avcodec_receive_frame may be unable to retrieve the decoded frame due to resource limitations.
2. Incorrect usage: It's possible that you may be using the function incorrectly, such as calling it too frequently or with the wrong parameters.
3. Unexpected input: If the codec encounters unexpected input or data, it may be unable to decode the frame properly, leading to the "Resource temporarily unavailable" error message.
To resolve this error, you may want to try the following steps:
1. Check your system resources: Ensure that your system has sufficient memory and processing power to handle the decoding task.
2. Verify function usage: Double-check that you are calling avcodec_receive_frame with the correct parameters and frequency.
3. Verify input data: Check that the input data being decoded is in the expected format and does not contain any unexpected data.
If none of these steps resolve the issue, you may want to consult the documentation for avcodec_receive_frame or seek assistance from a forum or support community for the specific codec or application you are using.
