| * | | proresenc: force bitrate not to exceed given limitKostya Shishkov2012-02-181-10/+62
| | | | | | | | | | | | | | | | | | | | | | | | Apple ProRes Format Specifications mentions target data size for every frame, so make sure frame meets it. This also allows encoder to demand much smaller packet sizes for output.
| * | | vc1parse: call vc1_init_common().Ronald S. Bultje2012-02-183-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The parser uses VLC tables initialized in vc1_common_init(), therefore we should call this function on parser init also. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
| * | | wma: don't return 0 on invalid packets.Ronald S. Bultje2012-02-181-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Return 0 means "please return the same data again", i.e. it causes an infinite loop. Instead, return an error. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
| * | | asf: prevent packet_size_left from going negative if hdrlen > pktlen.Ronald S. Bultje2012-02-181-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This prevents failed assertions further down in the packet processing where we require non-negative values for packet_size_left. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
| * | | mjpegb: don't return 0 at the end of frame decoding.Ronald S. Bultje2012-02-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Return 0 indicates "please return the same data again", i.e. it causes an infinite loop. Instead, return that we consumed the buffer if we finished decoding succesfully, or return an error if an error occurred.

| * | | rtpdec: Identify incorrectly signalled H263Martin Storsjö2012-02-183-10/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | H263 in RTP can be packetized in two formats (RFC 2190, RFC 2429/4629). The former normally uses the static payload type 34, while the latter normally uses dynamic payload types with the SDP format names H263-1998 or H263-2000. Look for packets that don't look like proper RFC 2190 packets and switch to depacketizing them according to the new format if they match some heuristic criteria.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This prevents SIGFPEs when using block_align for divisions. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

| * | | mp3on4: require a minimum framesize.Ronald S. Bultje2012-02-171-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If bufsize < headersize, init_get_bits() will be called with a negative number, causing it to fail and any subsequent call to get_bits() will crash because it reads from a NULL pointer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On EOF, get_bits() will continuously return 0, causing an infinite loop. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

| * | | movenc: Write track durations with all bits set if duration is unknownMartin Storsjö2012-02-181-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to 14496-12, the duration should be all 1s if the duration is unknown. This is the case if writing a moov atom without any samples described in it (e.g. as in ismv files). Signed-off-by: Martin Storsjö <martin@martin.st>
* | | | lavf-fate-ogg_vp3: Try -idct auto instead of -idct simple.Reimar Döffinger2012-02-182-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | -idct simple for some reason results in different results on different systems. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
* | | | oggenc: fix condition when not to flush due to keyframe granule.Reimar Döffinger2012-02-182-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous condition of 0 page size was wrong, that would disable the mechanism for all frames at a start of a page, thus some keyframes still would not get their own granule. The real problem is that header packets must not be flushed, but they have (and must have) 0 granule and thus would be detected as keyframes. Add a separate parameter to mark header packets.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to match Linux behaviour better our Windows-specific open() replacement should disable Windows default file locking. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
* | | | Make AAC in Ogg (ogm) work.Reimar Döffinger2012-02-181-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This needs the extradata to be extracted. The approach used is the one MPlayer uses, though it is unclear whether the 4 bytes extradata that are skipped should be skipped always or only for AAC. The AAC parser must be disabled, too, otherwise playback still does not work. Fixes trac issue #547. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
