Interesting tutorial on libav for sure but the submission title is definitely a bit of a stretch given that it's just a libav tutorial and you can probably do the same with ffmpeg directly quite easily. Can we change the title please?
- josteink 7y agoNot sure why you are being downvoted. I too assumed this was some minimalist from scratch C-project, not a guide to using ffmpeg.
- bluesign 7y agoAgreed "A minimalist encoder with libav" would be better
- ailideex 7y agoIt quite literally is not an encoder - title should be something like "how to use libav to convert H264 to H265" - libav is the only thing doing encoding here.
- userbinator 7y agoI thought it would be about finding a way to losslessly transform a H264 bitstream to a H265 one, and writing a simple application to do it. That would be a very interesting article if it was possible. Even the title of the page itself is (currently) "FFmpeg libav tutorial - learn how media works from basic to transmuxing, transcoding and more" which is far more accurate.
- fps_doug 7y agoThat's exactly what I expected. Now I'm really curious whether this is possible. Monsieur Bellard to the rescue please!
- leetcrew 7y agoignorant question: are h264 and h265 related in a way that would make this remotely possible?
- TD-Linux 7y agoBasically, no. Basic features like the transforms and loop filters are different. It would cause the result to rapidly differ after a few frames.
- spuz 7y agoFor reference, just in case the title is changed, it is currently: "A Minimalist Encoder, Written in C, to Convert H264 to H265"
- dang 7y agoSure, done now. You can get quicker responses on this by emailing us at hn@ycombinator.com. We don't come close to seeing everything posted to HN, and I only saw this randomly now.
