Michael Niedermayer	5f95c130a0	mov: Fix near infinite loop in stsd parsing. Fixes Ticket768 Bug found by: Diana Elena Muscalu Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	3383a53e7d	lavu: replace int/float punning functions The existing functions defined in intfloat_readwrite.[ch] are both slow and incorrect (infinities are not handled). This introduces a new header with fast, inline conversion functions using direct union punning assuming an IEEE-754 system, an assumption already made throughout the code. The one use of Intel/Motorola extended 80-bit format is replaced by simpler code sufficient under the present constraints (positive normal values). The old functions are marked deprecated and retained for compatibility. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	1fdf18f4b7	mov: add support for reading and writing the 'chan' tag This implements reading the tag in the demuxer and adds support for writing it in the muxer. Some example channel layout tables for muxing are included for ac3, aac, and alac, but they are not utilized yet.	13 years ago
Michael Niedermayer	e1ccc9216b	movdec: remove redundant size<=8 check. Its checked a few lines below too. The only difference is that empty atoms with size=0 will now get parsed too. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	7d90bc9f2a	movdec: Read extended 64bit size before the debug av_log() and only when there was enough space to read the 32bit size. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mihnea Balta	fef2da6a22	movdec: Fix bad computed size for atoms with size 0 in MOV files The computed size doesn't contain the header size because it's already skipped by incrementing total_size, but then it's skipped again in the last line. The atom comes out 8 bytes short and the function mov_read_chan() aborts the whole parsing process. I think the computed size should be atom.size - total_size + 8. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	f0d0ae3b1e	mov: increase total_size only when it actually increases. This is just cosmetic as the if() is always true. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Carl Eugen Hoyos	a448a5d1c4	Do not fail fatally if chan atom is too short.	13 years ago
Michael Niedermayer	b27ac355b7	movdec: Fix parsing of a very last empty atom of size 8. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Alex Converse	52401b82bd	mov: Don't av_malloc(0). malloc() is allowed to return NULL when zero is the argument. This causes us to think malloc has failed and return AVERROR(ENOMEM). In addition OS X malloc() returns an unfreeable non-NULL pointer for size zero when alignment is greater than 16.	13 years ago
Alex Converse	6d23d19729	mov: Allow empty stts atom. Fixes regressions caused by `30c3d976`	13 years ago

Carl Eugen Hoyos	8a3f976498	Support decoding "m1v " mpeg1video in mov. Fixes ticket #579 at least for ffplay.	13 years ago
Carl Eugen Hoyos	237f13290b	movdec: Set frame_size for AMR Earlier, sc->samples_per_frame was used for setting the frame size, but all files don't have that set properly. The frame size is a known constant for these codecs. If frame_size isn't set, the mov/3gp muxer refuses to mux it. This fixes stream copy of audio from https://roundup.libav.org/file1248/Video_With_AMR-NB_Audio.3gp to another 3gp file (roundup issue 2468). Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Hendrik Leppkes	b76bc01034	Implement parsing of the "HandlerName" from th MP4 HDLR atom. This atom typically is used for a track title.

Anton Khirnov	84ad31ff18	lavf: replace av_new_stream->avformat_new_stream part II. Manual replacements are done in this commit. In many cases, the id is some constant made up number (e.g. 0 for video and 1 for audio), which is then not used in the demuxer for anything. Those ids are removed.	13 years ago

Tomas Härdin	e571305a71	mov: Only touch extradata in mov_read_extradata() if codec_id is what we expect Extradata should only be parsed from the avss, fiel, jp2h and alac atoms for AVS, MJPEG, Motion JPEG 2000 and ALAC respectively.
