lavc/qsvenc_hevc : restore the default gop size
11 août 2023, par Haihao Xianglavc/qsvenc_hevc : restore the default gop size
commit a3c0a3e changed the default settings and expected the runtime can
choose a best value. However the runtime doesn't set a valid gop size
for hevc encoder, hence the output steam is non-seekable, which is
inconvenient to user [1][2][1] https://github.com/intel/media-driver/issues/1576

From this output i want to store : "HP True Vision HD Camera" (first video output) in a python variable.


Is this possible ?


I am trying

output = pipe.stdout
lines = output.splitlines()
for line in lines:
 if line.startswith("[dshow @"):
 if "(video)" in line:
 camera_info = line.split("\"")[1]
 print(camera_info)
