Anomalie #3575 (Nouveau) : Regression GD2
28 octobre 2015, par dani-belvil-net -Nomadgroup points out a functional regression on spip 3.0.20. compared to 3.0.17 :

I have an application in flask where it streams a camera using ffmpeg, the problem is that I can not display the video from the camera using the GPU [closed]
17 janvier, par RubenI'll put you in context, I am using flask (python) to display a camera in the browser to stream it, for this I use the following Python code :


command = [
 'ffmpeg',
 '-loglevel', 'warning',
 '-rtsp_transport', 'tcp',
 '-i', self.config['url'],
 '-map', '0:v:0', # fuerzo que solo procese el video
 '-vf', f'fps={self.config["fps"]},scale=640:360:force_original_aspect_ratio=decrease',
 '-c:v', 'h264_nvenc', # especificamos que queremos tirar de la gpu de nvidia
 '-preset', 'p7', # ajusta para la maxima calidad/velocidad (p1 mas rapida pero peor calidad - p7 más lento pero mejor calidad)
 '-qp', self.config['quality'], # control de calidad del codificador (0 [mejor calidad] - 51 [peor calidad])
 '-pix_fmt', 'yuv444p', # se mete explicitamente el formato de pixeles
 '-color_range', 'pc',
 '-an', # desactiva el audio
 '-f', 'image2pipe',
 'pipe:1'
] 

self.process = subprocess.Popen(
 command,
 stdout=subprocess.PIPE,
 stderr=subprocess.PIPE,
 bufsize=10**8
)


The problem is that it does not display the video streaming, but it connects correctly to the camera.


On the other hand, It show me the following warnings, which may have something to do with the display, it's probably the second warning that has to do with the pixel format :


DEBUG :main:FFmpeg [camera1] : Guessed Channel Layout for Input Stream #0.1 : mono
DEBUG :main:FFmpeg [camera1] : [swscaler @ 0x560f70b78680] deprecated pixel format used, make sure you did set range correctly


The server has different encodes installed :


DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders : h264 h264_v4l2m2m h264_qsv h264_cuvid ) (encoders : libx264 libx264rgb h264_nvenc h264_omx h264_qsv h264_v4l2m2m h264_vaapi nvenc nvenc_h264 )


Y uso el h264_nvenc, tambien el servidor tiene soporte de aceleración de hardware con :


libavutil 56. 70.100 / 56. 70.100
libavcodec 58.134.100 / 58.134.100
libavformat 58. 76.100 / 58. 76.100
libavdevice 58. 13.100 / 58. 13.100
libavfilter 7.110.100 / 7.110.100
libswscale 5. 9.100 / 5. 9.100
libswresample 3. 9.100 / 3. 9.100
libpostproc 55. 9.100 / 55. 9.100
Hardware acceleration methods :
vdpau
cuda
vaapi
qsv
drm
opencl


Between them h264_nvenc uses cuda
