We sspecify a bitrate of 10000k (-b:v 10000k), with a minimum bitrate of 9000k (-minrate 9000k), a maximum bitrate of 32000k (-maxrate 32000k) and a buffersize of 9000k I searched on Google, forums on FFmpeg Reddit and I did not find the solution to convert to this format of video quality and pixel. Also, this was never a problem when FFmpeg was used with the same encoder and pixel format. You signed out in another tab or window. Happy to see that you're experimenting with buffered readers and modifying VPF sources! Unlike pure Python, FFMpeg C API accepts file path in form of string (pointer to array of chars const char*) and it's very different from file descriptor.
