looking for supported muxers for x265enc

[hammerwerfer]

Hi,

 

i am trying to encode a UHD 4k video with gstreamer.

 

gst-launch.exe -e videotestsrc pattern=snow ! video/x-raw,width=3840,height=2160 ! queue ! x265enc ! matroskamux ! filesink location=test.mkv
WARNUNG: Fehlerhafte Leitung: x265enc0 konnte nicht mit matroskamux0 verknüpft werden

 

sorry for the german error message. must be something like could not link x265enc0 to matraskamux or similar.

 

gst-launch.exe -e videotestsrc pattern=snow ! video/x-raw,width=3840,height=2160 ! queue ! x265enc ! avimux ! filesink location=test.avi

results in same error message

 

 

The following works:

gst-launch.exe -e videotestsrc pattern=snow ! video/x-raw,width=3840,height=2160 ! queue ! x265enc ! mpegtsmux ! filesink location=test.ts

 

But my TV cannot play this file. What are other muxers i can try? Am i using the right encoder (x265) for 4k videos?

 

Thanks,

Jens

You can use qtmux which generates ISOMP4 commonly known as mov files.
Most TV should play those.

Hi,

 

thanks, but this results in the same error:

 

> gst-launch.exe -e videotestsrc pattern=snow ! video/x-raw,width=3840,height=2160 ! queue ! x265enc ! qtmux ! filesink location=test.mov
WARNUNG: Fehlerhafte Leitung: x265enc0 konnte nicht mit qtmux0 verknüpft werden

 

> gst-launch.exe --version
gst-launch-1.0 version 1.10.2
GStreamer 1.10.2

Try running <gst-inspect-1.0 -a | grep video/x-h265> to see what all muxers support H265 muxing

[Arjen Veenhuizen]

You need to insert h265parse between encoder and muxer.

Hi,

 

the output of gst-inspect is:

 

>gst-inspect.exe -a | grep video/x-h265
x265enc:       video/x-h265
h265parse:       video/x-h265

I was wondering that matroskamux is shown. So i tried my pipeline again with h265parse before x265enc and now it works. could not test it on my tv yet but i mkv has worked always.

My pipeline:

gst-launch.exe -v -e videotestsrc pattern=snow ! video/x-raw,width=3840,height=2160 ! x265enc ! h265parse ! matroskamux ! filesink location=test.mkv

 

Thanks,

Jens
