I now see that overflow occurs in the encoder device module (zero free buffers).
I see in ByteStreamFileSource.cpp that "fPreferredFrameSize" fits an
integral number of MPEG-2 TS packets into the MTU.
If I remove the the following in ByteStreamFileSource.cpp:
// Try to read as many bytes as will fit in the buffer provided
// (or "fPreferredFrameSize" if less)
if (fPreferredFrameSize > 0 && fPreferredFrameSize < fMaxSize) {
fMaxSize = fPreferredFrameSize;
}
and read as much data as is available,
12032 bytes (64 * 188) are read at a time instead of the usual 1316 (7 * 188).
Would a larger MTU likely help? Would that be moving into new
territory codewise?
Thanks for any pointers,
Gordon
