I want to play a recorded video stream in adtf3. I use a dat-file which was recorded in adtf2.
After following the example "demo_adtf2_video_decompressor_filter_session", I still get an error and the "Demo Qt Video Display" shows 'No valid video received yet'.

The error log in the console:

note: Codec jpeg not implemented

Any help from your side, how to get this to work?

Lösung

the situation is exactly as the error messages says, there is no jpeg codec implemented.
As the decompression filter says, only the rice codec is implemented:

• https://support.digitalwerk.net/adtf/v3/adtf_html/page_demo_adtf2_video_decompressor_filter.html

Feel free to extend regarding your needs, the filter comes as example with source code.
And the "old" compression toolbox sources are also open (as each un-migarted part of ADTF 2.x universe):

• https://git.digitalwerk.net/adtf2_open_source/adtf2_video_compression_toolbox

Here you can find a base for extending the support and "translate" to ADTF 3.x.

You must know, there is no support for compression yet in ADTF 3.x (thanks to customer forum), we are working on a new GStreamer possibility (Prototype see https://git.digitalwerk.net/adtf3_open_source/adtf3_video_toolbox) integrated in core or as open source addon, not defined yet.
But the "old" Video Compression is EOL and we only provide a quick solution for playback and IFHD support as you can see.

So please extend by yourself or make a order to us or anyone else if required.
