That is what you want. > coded_width/coded_height Encode a 126x126 video with x264, then use ffprobe to examine it and compare coded_width and width. > and also sample_aspect_ratio. PAL DVDs are 720×576, meant for 16:9. Do the math. The sample_aspect_ratio for PAL DVDs is 64/45. Do some more math. > There’s also AVStream->sample_aspect_ratio, display_aspect_ratio and > AVFrame->sample_aspect_ratio. These come from the stream, i.e. are obtained from the headers of the encapsulation format. The data in AVCodecContext comes after decoding the actual payload. Regards, -- Nicolas George
