* Add support for playing Audible AAXC (.aaxc) files [PATCH v4]Vesselin Bontchev2020-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AAXC container format is the same as the (already supported) Audible AAX format but it uses a different encryption scheme. Note: audible_key and audible_iv values are variable (per file) and are externally fed. It is possible to extend https://github.com/mkb79/Audible to derive the audible_key and audible_key values. Relevant code: def decrypt_voucher(deviceSerialNumber, customerId, deviceType, asin, voucher): buf = (deviceType + deviceSerialNumber + customerId + asin).encode("ascii") digest = hashlib.sha256(buf).digest() key = digest[0:16] iv = digest[16:] # decrypt "voucher" using AES in CBC mode with no padding cipher = AES.new(key, AES.MODE_CBC, iv) plaintext = cipher.decrypt(voucher).rstrip(b"\x00") # improve this! return json.loads(plaintext) The decrypted "voucher" has the required audible_key and audible_iv values. Update (Nov-2020): This patch has now been tested by multiple folks - details at the following URL: https://github.com/mkb79/Audible/issues/3 Signed-off-by: Vesselin Bontchev <vesselin.bontchev@yandex.com>
* avformat/mov: Only read the mfra size once during sidx parsingDerek Buitenhuis2020-09-03
| | | | | | | | | | | On files with more than one sidx box, like live fragmented MP4 files, it was previously re-reading and seeking on every singl sidx box, leading to extremely poor performance on larger files, especially over the network. Only do it on the first one, and stash its result. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* avformat/mov.c: require tfhd to begin parsing trunchcunningham2019-02-08
| | | | | | | | | | Detecting missing tfhd avoids re-using tfhd track info from the previous moof.

* Use QT format for audio sample descriptors depending on stsd version.Justin Ruggles2018-09-09
| | | | | | | | | | | | | | | | | ISOBMFF does not allow AudioSampleEntryV1 in stsd version 0, so assume the descriptor format is QTFF SoundDescriptionV1. ISOBMFF does not define a version 2. This fixes audio decoding for some MP4 files generated with Apple tools. The additional fields present in SoundDescriptionV1/V2 need to be read in order to correctly read additional boxes that contain information required for decoding the stream. Fixes #7376.

| | | | | | | | | | | | | | | | | | | | | | | | When keyframe intervals of dash segments are not perfectly aligned, fragments in the stream can overlap in time.

* | avformat/mov: Fix trampling of ctts during seeks when sidx support is enabled.Dale Curtis2017-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When sidx box support is enabled, the code will skip reading all trun boxes (each containing ctts entries for samples inthat box). If seeks are attempted before all ctts values are known, the old code would dump ctts entries into the wrong location. These are then used to compute pts values which leads to out of order and incorrectly timestamped packets. This patch fixes ctts processing by always using the index returned by av_add_index_entry() as the ctts_data index. When the index gains new entries old values are reshuffled as appropriate. This approach makes sense since the mov demuxer is already relying on the mapping of AVIndex entries to samples for correct demuxing. As a result of this all ctts entries are now 1-count. A followup change will be submitted to remove support for > 1 count entries which will simplify seeking. Notes for future improvement: Probably there are other boxes (stts, stsc, etc) that are impacted by this issue... this patch only attempts to fix ctts since it completely breaks packet timestamping. This patch continues using an array for the ctts data, which is not the most ideal given the rearrangement that needs to happen (via memmove as new entries are read in). Ideally AVIndex and the ctts data would be set-type structures so addition is always worst case O(lg(n)) instead of the O(n^2) that exists now; this slowdown is noticeable during seeks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The current behavior may produce a different sequence of packets after seeking, compared to demuxing linearly from the beginning. This is because the MOV demuxer seeks in each stream individually, based on timestamp, which may set each stream at a slightly different position than if the file would have been read sequentially. This makes implementing certain operations, such as segmenting, quite hard, and slower than need be. Therefore, add an option which retains the same packet sequence after seeking, as when a file is demuxed linearly.
