#3726 reopened defect

mpeg4 vdpau decoding failed

Reported by: Ilya87 Owned by:

Version: git-master Keywords: vdpau regression

Description

Summary of the bug:
How to reproduce:

My OS' configuration is Arch Linux x86_64, libvdpau 0.7, nvidia driver 337.25, GeForce GTX 560, ffmpeg built 17.06.2014 15:26 MSK from git
Every time I play mpeg4 part2 encoded files using QMPlay2 (with VDPAU) I have the following error (and no image obviously):
[mpeg4 @ 0x1b05120] Image too small, temporary buffers cannot function                
[mpeg4 @ 0x1b05120] get_buffer() failed to allocate context scratch buffers.
Without VDPAU all is OK.

The same situation repeats with mplayer -vc ffodivxvdpau -vo vdpau "file.avi"
[mpeg4 @ 0x7fd25a5ff380]Image too small, temporary buffers cannot function
[mpeg4 @ 0x7fd25a5ff380]get_buffer() failed to allocate context scratch buffers.
Error while decoding frame!
And again all is good with decoding using -vc ffodivx
ffplay -decoders show me the following:
V....D mpeg4_vdpau          MPEG-4 part 2 (VDPAU) (codec mpeg4)

Ditto. ffmpeg-4* seems to have reintroduced this bug using mplayer-1.3.0-r5, when using NVidia vdpau/ffmpeg12vdpau. (Using ffmpeg-4.1)
