Hi,
Do you use r32.4.3? We enable hardware decoding in ffmpeg from r32.4.3. Previous release doesn’t support it.

#4

No, R28 (release), REVISION: 2.0. Is there a way to use ffmpeg without hardware decoding? I just want it to work, I don’t need it to be fast

#5

Hi,
On r28 release(2), ffmpeg with hardware acceleration is not supported. Suggest use gstreamer and jetson_multiedia_api.

And if you use TX2, we would suggest upgrade to r28.2.1. We only support r28.2/TX1. Please check

NVIDIA Tegra Linux Driver Package supports development for the following platform:

* NVIDIA® Tegra® X1 series (Jetson TX1)

Hi, that does not answer my question.

What I would like to know is whether it’s possible to install and use ffmpeg on my version with only cpu decoding (not with hardware acceleration).

Thanks!

Hi there, following up on this

#8

Hi,
You can install the package through

$ sudo apt install ffmpeg

Or download the source code package and compile it:

Perhaps you just didn’t read the prior parts of this thread. This does not work.

ffmpeg: symbol lookup error: /usr/lib/aarch64-linux-gnu/libavdevice.so.58: undefined symbol: drmModeFreeFB
#10

Hi,
Please refer to the post:


Pease try to hard link libdrm.so.2 to correct file.

#11

I tried to link libdrm.so.2 to the correct file with

sudo rm /usr/lib/aarch64-linux-gnu/libdrm.so.2
sudo -H ln -s /usr/lib/aarch64-linux-gnu/libdrm.so.2.4.0 /usr/lib/aarch64-linux-gnu/libdrm.so.2

but it remains in a broken state:
ffmpeg: symbol lookup error: /usr/lib/aarch64-linux-gnu/libavdevice.so.58: undefined symbol: drmModeFreeFB

#12

Hi,
Are you able to down the source code and build it on TX2? Since r28 release(s) is old, maybe try ffmpeg2.6.9 or 3.3.9.

#13

Yes, rebuilding ffmpeg 3.4.8 works just fine. Since many of the devices I maintain are in remote settings and require cellular data to be updated, I would prefer to avoid having to push an update as large as the ffmpeg package.

Do you think there may be a smaller change I can make, or am I stuck with the solution of pushing a wholly new ffmpeg version?
