Comment (by dkode):

 @Bailing

 I don't this it is required and functionally the process is working fine.I
 have a requirement that software decoding cannot be used (software decoder
 explicitly disabled using disable-decoder flag while compiling).

 Al thought functionally correct, But it is super slow for tile based heic
 images.I could see in the logs that cuda is getting opened and closed a
 lot of times, this may be the reason. Please find the trace logs attached
 above.
