Little endian codec for windows

Opened 9 years ago. Closed 9 years ago. So audio is Little Endian. However, ffmpeg interprets the tracks as Big Endian, so audio is not decoded properly. To give a little bit more info, if I run ffprobe, you can see that ffmpeg thinks the audio is Big Endian:. I could provide the example MOV file but it's Mbytes. I'll try to produce a much smaller example to reproduce the problem easily and attach it later. I tried, however I'm afraid it is a limit, since I got this error message: "Maximum attachment size: bytes".

Thanks for your help cehoyos. I don't know if it's a regression. Just ask. I've been investigating a little bit further how the endianess should be specified in the 'in24' codec.

I attached a screenshot of dumpster. So, I guess that for some reason ffmpeg does not parse this atom correctly. Bitcoin likes using little-endian format for some data, so when working with code, you often have to get things in to little-endian format for them to work.

When you read it from left to right, you start with the most-significant value first i. But if you think about it, it could make just as much sense to start with the little-end first.

And so by reversing 2 characters 1 byte at a time, we get in little-endian:. This is just a quick way of getting a string in to little-endian. Swap Endian - a basic tool that converts between little-endian and big-endian format and vice-versa. Precision conversions can be performed using simple bit shifts. The bit representations described here use little-endian WORD values for each channel. The bit formats also use 16 bits for each channel, with the lowest 6 bits set to zero, as shown in the following diagram.

Because the bit and bit representations of the same YUV format have the same memory layout, it is possible to cast a bit representation to a representation with no loss of precision. It is also possible to cast a bit representation down to a bit representation. The Y and Y formats are an exception to this general rule, however, because they do not share the same memory layout. When the graphics hardware reads a surface that contains a bit representation, it should ignore the low-order 6 bits of each channel.

If a surface contains valid bit data, however, it should be identified as a bit surface. Alpha is assumed to be a linear value that is applied to each component after the component has been converted into its normalized linear form. For images in video memory, the graphics driver selects the memory alignment of the surface. That is, individual lines within a surface are guaranteed to start at a bit boundary, although the alignment can be larger than 32 bits. The origin 0,0 is always the upper-left corner of the surface.

For the purposes of this documentation, the term U is equivalent to Cb , and the term V is equivalent to Cr. If the format is packed, the first character is 'Y'. The final two characters in the FOURCC indicate the number of bits per channel, either '16' for 16 bits or '10' for 10 bits. No formats for bit or bit YUV have been defined at this time.
