Pete Eberlein	b4f81b7429	Add a mapping for the V4L2_PIX_FMT_NV12 format to PIX_FMT_NV12 for video4linux2 devices. This is used by Sensoray Model 2253 cards. Patch by Pete Eberlein (pete AT sensoray DOT com) Originally committed as revision 24759 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	6ce9b4310c	Remove use of the deprecated function avcodec_check_dimensions(), use av_check_image_size() instead. Originally committed as revision 24711 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	50f852186f	Make device_open() store the VIDIOC_QUERYCAP ioctl errno, and in case of failure return the stored value rather than the current errno, which may be overwritten by a following call to close(). Originally committed as revision 23001 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Luca Abeni	b01dba14f3	Check the return value of device_try_init() immediately after calling such a function. Avoids the following warning: libavdevice/v4l2.c: In function ‘v4l2_read_header’: libavdevice/v4l2.c:586: warning: ‘codec_id’ may be used uninitialized in this function Originally committed as revision 22986 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	6e25b78001	Fix weird brace placement. Originally committed as revision 22982 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Luca Abeni	4f54d924bc	Simplify some output messages in the v4l2 input device Originally committed as revision 22979 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	932d775fa2	Implement v4l2 input size autodetection in v4l2_read_header(). Move check on frame size after the device is opened and after device_try_init() is attempted. If the provided size value is 0x0, perform a VIDIOC_G_FMT ioctl() on the device, which sets size to the current settings. Originally committed as revision 22971 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	c57a8fefd9	Return meaningful error codes, rather than always -1. Originally committed as revision 22966 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jai Menon	90d0379f5e	Avoid using deprecated AVFormatParameters::[audio\|video]_codec_id field. Originally committed as revision 21511 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Luca Abeni	9eb6e9d9d3	Add support for V4L2 compressed formats in the table used for converting between V4L2 formats and ffmpeg's formats/codecs. Patch by klchxbec AT freenet DOT de. Originally committed as revision 20857 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Luca Abeni	9202218e5d	Use the correct type for the V4L2 format. Originally committed as revision 20856 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Luca Abeni	158aa9f2db	Return pkt->size in v4l2_read_packet(). mmap_read_frame() takes care of ensuring that the packet size is correct. Originally committed as revision 20855 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Luca Abeni	1c787b1043	Cast a __u64 variable to uint64_t so that it can be printed without warnings Originally committed as revision 17325 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Luca Abeni	5449a787c9	If AVPacket->data == NULL, the packet does not contain any buffer to be freed. This fixes a double free on exit. Originally committed as revision 16857 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	406792e7b0	cosmetics: Remove pointless period after copyright statement non-sentences. Originally committed as revision 16684 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Aurelien Jacobs	b250f9c66d	Change semantic of CONFIG_, HAVE_ and ARCH_*. They are now always defined to either 0 or 1. Originally committed as revision 16590 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Luca Abeni	e7b987dc2f	Remove the frame rate from struct video_data, and allow using a variable frame rate for video4linux2 input Originally committed as revision 16464 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	5d91e92853	Use avcodec_check_dimensions() for checking the frame size validity. The v4l.c check is moved after the eventual automatic size detection, so the check in that case is performed on the new set values. Originally committed as revision 16370 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	df2a3f2714	Use more descriptive long_names for Video4Linux input devices. Originally committed as revision 16322 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Jens Rosenboom	3d0d9a5e3b	The v4l2 driver can silently change the pixel format in the VIDIOC_S_FMT ioctl(). In this case, device_init() should fail so that a different pixel format is tried. Patch by Jens Rosenboom (jens DOT rosenboom AT eu DOT panasonic DOT com) Originally committed as revision 15660 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Stefano Sabatini	99423fa0ee	Distinguish the error reporting for the cases of wrong size and wrong timebase in the video4linux2 v4l2_read_header() function. Originally committed as revision 14647 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Stefano Sabatini	deaab5fc32	Make v4l2_read_header() don't free a stream in case of failure when reading its header. The stream will be freed later in av_open_input_stream(). Fix a segmentation fault due to a double free on the same pointer. Originally committed as revision 14247 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Stefano Sabatini	bde15e74de	Make long_names in lavf/lavdev optional depending on CONFIG_SMALL. patch by Stefano Sabatini, stefano.sabatini-lala poste.it along with some spelling/consistency fixes for the long names by me Originally committed as revision 13649 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Carl Eugen Hoyos	eacced45c4	Replace some occurrences of -1 with PIX_FMT_NONE. Fixes icc warning #188: enumerated type mixed with another type Originally committed as revision 13130 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Diego Biurrun	245976da2a	Use full path for #includes from another directory. Originally committed as revision 13098 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Diego Biurrun	0e58bf670d	Remove #ifdef HAVE_SYS_MMAN_H around sys/mman.h #include. Without the #include compilation fails. Originally committed as revision 12568 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Diego Biurrun	b00675499c	Only #include sys/mman.h if configure set HAVE_SYS_MMAN_H. Originally committed as revision 12521 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michel Bardiaux	48f7e1aeee	Clarify the error message when video width, height, or framerate are not specified. Patch by Michel Bardiaux (mbardiaux AT mediaxim DOT be) Originally committed as revision 11551 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Luca Abeni	653387d8f0	Support for the AVFMT_FLAG_NONBLOCK flag (non-blocking input) in v4l2.c Originally committed as revision 9496 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Luca Abeni	e4dd03f395	Reindent code after last commit Originally committed as revision 8973 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Luca Abeni	41536a6078	Pass the v4l2 buffer into the AVPacket, instead of allocating a new buffer and copying the frame into it (remove a memcpy()) Originally committed as revision 7981 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
François Revol	8fa36ae09d	This fixes error handling for BeOS, removing the need for some ifdefs. AVERROR_ defines are moved to avcodec.h as they are needed in there as well. Feel free to move that to avutil/common.h. Bumped up avcodec/format version numbers as though it's binary compatible we will want to rebuild apps as error values changed. Please from now on use return AVERROR(EFOO) instead of the ugly return -EFOO in your code. This also removes the need for berrno.h. Originally committed as revision 7965 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
