| * movenc: Buffer the mdat for the initial moov fragment, tooMartin Storsjö2012-02-222-24/+51
| | | | | | | | | | | | | | | | | | | | | | | | This allows writing QuickTime-compatible fragmented mp4 (with a non-empty moov atom) to a non-seekable output. This buffers the mdat for the initial fragment just as it does for all normal fragments, too. Previously, the resulting atom structure was mdat,moov, moof,mdat ..., while it now is moov,mdat, moof,mdat. Signed-off-by: Martin Storsjö <martin@martin.st>

| * movdec: Don't parse all fragments if ignidx is setMartin Storsjö2012-02-221-2/+3
| | | | | | | | | | | | | | | | | | | | In nonseekable files, we already stop parsing the toplevel atoms after finding moov and one mdat. In large seekable files (or files that are seekable, but slowly, e.g. http), reading all the fragments at the start can take a considerable amount of time. This allows opting out from this behaviour.

| * movdec: Restart parsing root-level atoms at the right spotMartin Storsjö2012-02-222-3/+10
| | | | | | | | | | | | | | | | | | | | | | If parsing moov+mdat in a non-seekable file, we currently abort parsing directly after parsing the header of the mdat atom. If we want to continue parsing later (if looking to parse later fragments), we need to skip past the content of the mdat atom, otherwise we end up parsing the content of the mdat atom as root level atoms.

| * prores: use natural integer type for the codebook indexChristophe GISQUET2012-02-222-3/+3
| | | | | | | | | | | | | | | | | | | | | | The operations that use it require it to be promoted to a larger (natural) type and thus perform sign extension on it. While an optimal compiler may account for this, gcc 4.6 (for x86 Windows) fails. Using the natural integer type provides a 2% speedup for Win64 and 1% for Win32.

| * movdec: Adjust keyframe flagging in fragmented filesMartin Storsjö2012-02-211-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For video, mark the first sample in a trun which doesn't have the sample-is-non-sync-sample flag set as a keyframe. In particular, the "sample does not depend on other samples" flag isn't enough to make it a keyframe, since later frames still can reference frames prior to that one (the flag only says that that particular frame doesn't depend on other frames). This fixes bug 215. Signed-off-by: Martin Storsjö <martin@martin.st>
| * rv34: change most "int stride" into "ptrdiff_t stride".Ronald S. Bultje2012-02-207-30/+30
| | | | | | | | | | | | This prevents having to sign-extend on 64-bit systems with 32-bit ints, such as x86-64. Also fixes crashes on systems where we don't do it and arguments are not in registers, such as Win64 for all weight functions.

| | | | | | | | | | | | Mostly based on doc/examples/filtering.c. lavfi API is still limited to "buffer feeding" instead of "frame feeding" at the moment, so this example code sticks with it.
* | lavfi/abuffer: init the data planes with NULL pointers.Clément Bœsch2012-02-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | Samples buffer ref is allocated and loaded with the uninitialized data pointers: av_asrc_buffer_add_buffer() -> av_asrc_buffer_add_samples() -> avfilter_get_audio_buffer_ref_from_arrays(data, ...) ...which leads to a crash with at least lavfi/ashowinfo in case of !NULL (see the for loop while samplesref->data[plane]).
