encode

问题 I'm tring to concatenate two strings encoded to base64 but it doesn't really work, just prints the first string in concatanation: q = base64.b64encode("StringA") print q # prints an encoded string q = q+base64.b64encode("StringB") print q # prints an encoded string print base64.b64decode(q) # just prints "StringA" 回答1: You are decoding a string that is concatenation of two base64 strings. This is not correct. You should do something like this - base64.b64decode(base64.b64encode("StringA" +

问题 What I want to do: extract text information from a pdf file and redirect that to a txt file. What I did: pip install pdfminor pdf2txt.py file.pdf > output.txt What I got: UnicodeEncodeError: 'gbk' codec can't encode character '\u2022' in position 0: illegal multibyte sequence My observation: \u2022 is bullet point, • . pdf2txt.py works well without redirection: the bullet point character is written to stdout without any error. My question: Why does redirection cause a python error? As far as

问题 My problem is very fast to explain: I have to encode audio samples using FFmpeg (raw PCM to G.711 mu-law). This is the guilty part of my code (I put raw parameters in this example to be explicit): AVFrame* frame = av_frame_alloc(); frame->nb_samples = 8000; frame->format = AV_SAMPLE_FMT_S16; frame->channels = 1; frame->channel_layout = AV_CH_LAYOUT_MONO; frame->sample_rate = 8000; frame->quality = 1; int res = avcodec_fill_audio_frame(frame, 1, AV_SAMPLE_FMT_S16, /*my samples data*/, 16000, 0
