search for: teletext

...alone, as it would just be yet another half-baked adhoc "standard" that causes more problems than it solves. For example I had not even considered the idea of using multiple files. On the topic of seeking, it is also a problem for my specific use case. I am interested in digital signals (teletext) hidden in analog video (CVBS samples), and they just aren't sequential in the same way that audio and video usually are. I need to seek to an arbitrary video line as fast as possible, preferably in constant time. A line is usually 2048 samples but can vary between 1000 and 3000 samples long (a...

...issue. But for bit depth it is not needed, libflac allows 4 to 32 bit per sample, with all values in between. Total samples and sample rate are the only fields I can think of. > > On the topic of seeking, it is also a problem for my specific use case.
