| Summary | 0000035: decode_one_frame() now decodes all frames! | ||||
| Description | Because the check in exit_macroblock() for setting currSlice->next_header = SOP was commented out, it is now the case that the while loop in decode_one_frame() never exits until EOS. The big problem with this is that one cannot implement applications, such as frame accurate players, that need to decode one frame and then stop. Also, this code is now silly, because decode_one_frame() decodes the entire stream and does not return after each frame: while (decode_one_frame(img, input, snr) != EOS) | ||||

The whole decoding loop needs some reviewing, especially regarding new picture detection in error cases (also with data partitioning). I already have this on my ToDo list for quite a while, but it's low priority for me. |
