Hi.
I am using Pi 5 with v3 camera. I am trying to have audio stream and uncompressed video stream in the same time.
Currently, I am using libcamera-vid command that can generate a stream containing both Audio and Video. And the resulting file is correct and can be played by ffplay. BUT, video stream is compressed...
Then I tried the following command :
an mkv file is generated but when trying to ffplay it, the following error message occurs : « EBML header parsing failed test20.mkv: Invalid data found when processing input ».
FYI, I switched to mkv container because it works when I generate only YUV420 data. I mean file is generated and played by ffplay.
I am trying to tune the different parameters and options of format and codec( ffmpeg_codecs options include the format yuv4 Uncompressed packed 4:2:0), with no success.....
