Python and SQL BLOB Streaming - ashtona - May-08-2018 Hello, I have some videos I am storing on an SQL BLOB column. Is there a way I could read from the columns in byte chunks to create a stream in python? Any help on this would be greatly, greatly appreciated. RE: Python and SQL BLOB Streaming - Larz60+ - May-08-2018 this looks to be about reading blob data in chunks, (SQL Server): https://stackoverflow.com/questions/13777840/how-do-i-select-just-a-portion-of-huge-binary-file?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa RE: Python and SQL BLOB Streaming - ashtona - May-09-2018 Ok so I can get the bytes, is there a way I can convert them to a image using PIL or something and feed them to a video player? Thanks RE: Python and SQL BLOB Streaming - Larz60+ - May-09-2018 Please refer to: https://code-maven.com/create-images-with-python-pil-pillow as there are several writing modes, including text. RE: Python and SQL BLOB Streaming - ashtona - May-09-2018 Read through that, still not sure how I can shove bytes in there to create an image. If I have the bytes there has to be a way to get frames out of them right? How else are streams created? I tried this image.open(io.BytesIO(values[0][0])) my values[0][0] contains a portion of my video file in bytes I get this error cannot identify image file <_io.BytesIO object at 0x0000025D891FF200>. |
