c2_aml_libs's Issues

Warning of Debian Package

I'd like to report:

apt-get installing
gstreamer-aml libplayer-aml
made alsa unusable on my khadas VIM3.

I listen to audio on a USB soundcard (alsa 1,0) and the debian libplayer-aml package replaces libasound.

This resulted in a never-seen-before situation where programs targeting device (1,0) would play back through HDMI, and no change to /etc/asound.conf could fix.

Purging the package and reinstalling libasound did not restore normal operation - alsa refuses to accept (1,0) as default device. But now I can at least send one stream to the USB soundcard by specifying the alsa device at program invocation.

I just wanted the issue reported in a place people may be likely to find it. If anyone has further info on what happened, I'd be happy to read it.

Thanks!

Compilation errors GCC 5.4.0/Glibc

Hello,

I am writing an ebuild for Gentoo.

When the compilation of the libs is complete, I have a pretty list of warnings, that I would like to get rid of.

Compilation is done directly on the c2.

Decoding latency after writing bitstream data to decoder

Hi! I used
After starting sending data to codec_write() there is a latency 100-200ms (milliseconds) after we get resulting image to a screen (fb0/fb1). For testing this issue I used simple example of video decoding (with an h264 raw bitstream). If we stop bitstream sending via codec_write() finction call, we do not obtain all the frames. Seems like there is kind of buffering or something.
Is it a bug or a feature? The latency between codec_write and screen output is up to 23 (twenty three) frames.
Is there any way to set 0-buffering to have 1in=>1out decoding?

p.s. This issue is observerd in
