There is an implicit variable here, which is the actual remaining bits. So the error message should include this information.

return srs_error_new(ERROR_HEVC_DECODE_ERROR, "ptl requires 88 only %d bits", bs->bits_left());

Note: There is no need to write so many constants. The errors already include line numbers and functions, so we only need a descriptive constant. Therefore, instead of ptl general profile tier shall atleast, it can be directly changed to ptl requires or ptl profile requires.

Please also make changes in other places.
