ffplay doesn't work with libvdpau-sunxi

[slapin]

I'm using armbian. When I recompile ffmpeg from deb-multimedia to support vaapi and vdpau, and then try to use vdpau, I get crashes with git master, and with version included in armbian. ffmpeg version is 2.6.9.

Is there something I can do to make it work or to provide better bug report?

need to mention, that mpv bundled with armbian works fine, but nothing else.

ffplay doesn't work with any vdpau, it even crashes on x86 with these parameters. ffmpeg (library) supports vdpau, but ffplay doesn't as far as I know. (https://ffmpeg.org/pipermail/ffmpeg-user/2012-July/008121.html) mpv, mplayer, vlc are all working pretty well with every vdpau implementation, including vdpau-sunxi, gstreamer is said to be working too, but I haven't tried it yet.

Does that mean that current firefox (the one you get checking-out using hg) (which uses ffmpeg) should work too?

I don't know, if it supports vdpau (and doesn't need any opengl interop features) it pobably could. But it looks like firefox doesn't support vdpau: https://bugzilla.mozilla.org/show_bug.cgi?id=1210729#c12

Both Firefox and Chromium do support vaapi (via Xv or when forced, as I understand) and there are drivers which support vdpau as vaapi backend, but this also looks like depend on Xv. Chromium supports vaapi via patch and Firefox supports vaapi via gstreamer1.0-vaapi or (newer versions) via ffmpeg. The problem is I can't make vaapi-vdpau work :( as it expects Xv to be working, and it doesn't work on armbian for some reason...

I can't help your there, none of the things you mentioned has anything to do with vdpau. If for any reason the vaapi driver has problems with vdpau-sunxi we can try to fix it, but currently your problems seem to be way before even touching vdpau.
