Description

Hello guys, to be honest I am not even sure if this is the right place to report this but anyways here it goes.

I am experiencing a issue with interlaced h264 and separate fields on my Fire TV Stick (2nd Gen) which leads to the image looking messy, example: https://imgur.com/a/gGvOrKI

Already reported this on MPV's Github: https://github.com/mpv-android/mpv-android/issues/129

According to the user/dev tmm1 there seems to be a fix for this (http://ffmpeg.org/pipermail/ffmpeg-devel/2018-June/231237.html) but it isn't implemented yet.

A sample file to reproduce this issue can be found over here: https://www65.zippyshare.com/v/CbDWPgBB/file.html

Anything else you might need, just let me know!

The patch I proposed does not fix this issue on the FireTV stick. And, as I noted on the mailing list, the technique used in my patch is invalid according to the MediaCodec? documentation. So at this time there is no known fix for this issue.

Thanks for the clarification!

Well, then the ticket isn't placed that bad over here, I guess.

If there is anything I can do to contribute to narrow down this issue (e.g. logs, etc.) just let me know!
