Diego Biurrun	4978850ca2	build: Split JPEG-related tables off into a separate component	10 years ago
Martin Storsjö	d594dbecce	rtpdec: Rename the free method to close Many of these functions were named foo_free_context, and since the functions no longer should free the context itself, only allocated elements within it, the previous naming was slightly misleading. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Martin Storsjö	199fb40278	rtpdec: Use ffio_free_dyn_buf Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Martin Storsjö	bb4a310bb8	rtpdec: Don't free the payload context in the .free function This makes it more consistent with depacketizers that don't have any .free function at all, where the payload context is freed by the surrounding framework. Always free the context in the surrounding framework, having the individual depacketizers only free any data they've specifically allocated themselves. This is similar to how this works for demuxer/muxers/codecs - a component shouldn't free the priv_data that the framework has allocated for it.

Martin Storsjö	88434f9725	rtpdec: Remove unnecessary inline attributes These functions are far from performance critical, so there's no point in marking them as inline. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Martin Storsjö	5d8cae4573	rtpdec: Get rid of all trivial .alloc/.free functions Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Martin Storsjö	db158f0dd2	rtpdec: Remove unnecessary _if_needed suffixes on functions Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Martin Storsjö	90c784cc13	rtpdec: Pass the sequence number to depacketizers This allows depacketizers to figure out if packets have been lost. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	511cf612ac	miscellaneous typo fixes	12 years ago
Anton Khirnov	179a5c37e0	rtpdec: factorize identical code used in several handlers	12 years ago
Martin Storsjö	c3bcd22ed3	rtpdec_jpeg: Error out on other unsupported type values as well Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	1743938df1	rtpdec_jpeg: Disallow using the reserved q values Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	1de9317bd0	rtpdec_jpeg: Fold the default qtables case into an existing if statement Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	a218deb856	rtpdec_jpeg: Store and reuse old qtables for q values 128-254 Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	a252649059	rtpdec_jpeg: Simplify the calculation of the number of qtables Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	cbaa9eeda3	rtpdec_jpeg: Add more comments about the fields in the SOF0 section Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	31adff08a1	rtpdec_jpeg: Clarify where the subsampling magic numbers come from Write out the numbers the way they are constructed, not just the final values. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	c64d2a63df	rtpdec_jpeg: Don't use a bitstream writer for the EOI marker Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	20f325f320	rtpdec_jpeg: Don't needlessly use a bitstream writer for the header Everything written with this bitstream writer is 8/16 bit units (except for a pair of 4 bit values), so using a bitstream writer isn't necessary. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	43957fcc71	rtpdec_jpeg: Simplify writing of the jpeg header Generalize writing of any number of qtables. Don't manually write 16 bit values in two separate calls. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	932d8300d3	rtpdec_jpeg: Merge two if statements This makes the code more readable and robust. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	7ef4323405	rtpdec_jpeg: Write the DHT section properly Currently the size header of the generated DHT section is incorrect, making the mjpeg decoder just skip it. Since the written huffman tables are the default ones, this failure had gone undetected. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Samuel Pitoiset	55e778bebd	rtpdec_jpeg: Add support for default quantizers Generate quantization tables when they are not present in the first chunk. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Samuel Pitoiset	3c19815416	rtp: Depacketization of JPEG (RFC 2435) Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
