x265 already safe for use?

Hi, is x265 still considered experimental or is it safe to use? That is, does it produce standard-conformant files so that I will not have problems later with playing them back (1.7 with 10bit enabled)?

I encoded some movies I recorded with my Canon EOS 550D, and so far I was very impressed by the compression ratio and the quality achieved. The quality of the recordings is not so great nor are they so important that I want to keep the original files.

Unfortunately, I cannot really reply to your question, as I am kind of in the same situation. However, the ffmpeg site says: 'Note: libx265 is under heavy development. The API may change.' Therefore, I am hesitant to convert all my videos to H.265 for now.

If you want to be safe, consider using VP9 instead. The quality difference is negligible, it's more technically mature, and it also doesn't have a looming threat of patent-licensing extortion - though if you used x264 you probably don't care about this last point.

I do not think you'd have problems to play back x265 content, the problems may be with encoding. OTOH, recoding should be always avoided because we are dealing with lossy codecs, I wouldn't recode any of my MPEG-4 Part 10 (which is AVC or x264) to x265 only because I can.

So far, I have made very good experiences with 1.8 and 1.9. It is also reasonably fast now. Important videos won't be converted anytime soon though.
