带 VDPAU 的 GStreamer(使用 nVidia 卡进行 h264 加速)
我使用最新版本的 gstreamer 插件很糟糕,我想尝试 VDPAU。 我用搅拌机基金会的大兔子电影进行了测试。 我尝试过这个命令: gst-launch-0.10 filesrc=/home/alex/big.mp4 ! mp4复用器! vdpauh264dec ! vdpau视频后处理! vdpausink
但它无法将 mp4mux 与 vdph264dec 链接。
我还尝试使用 ffdemux_mov_mp4_m4a_3gp_3g2_mj2 而不是 mp4mux 和 gst-launch 失败,但出现错误消息:
[...]
Could not create vdpau decoder
[...]
Error returned from vdpau was: An invalid/unsupported VdpDecoderProfile value was supplied
[...]
How can I play h264 with VDPAU features of my NVIDIA 卡?
预先感谢您的任何帮助,请原谅我的英语不好。
问候,
I use last version of gstreamer plugins bad and I would like to try VDPAU.
I test with the big buck bunny movie from blender foundation.
I've try with this command :gst-launch-0.10 filesrc=/home/alex/big.mp4 ! mp4mux ! vdpauh264dec ! vdpauvideopostprocess ! vdpausink
but it could not link mp4mux with vdph264dec.
I also tried with ffdemux_mov_mp4_m4a_3gp_3g2_mj2 instead of mp4mux and gst-launch fail but with an error message :
[...]
Could not create vdpau decoder
[...]
Error returned from vdpau was: An invalid/unsupported VdpDecoderProfile value was supplied
[...]
How can I play h264 with VDPAU capabilities of my NVIDIA card?
Thanks in advance for any help, and please excuse my bad english.

mp4mux 是一个复用器,而不是一个解复用器。您确实应该使用 ffdemux_mov_mp4_m4a_3gp_3g2_mj2。以下命令行对我有用:
mp4mux is a muxer, not a demuxer. You should indeed use ffdemux_mov_mp4_m4a_3gp_3g2_mj2. The following command line worked for me:
