* avformat/smacker: Improve timestampsAndreas Rheinhardt2020-07-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A Smacker file can contain up to seven audio tracks. Up until now, the pts for the i. audio packet contained in a Smacker frame was simply the end timestamp of the last i. audio packet contained in an earlier Smacker frame. The problem with this is that a Smacker stream need not contain data in every Smacker frame and so the current i. audio packet present may come from a different underlying stream than the last i. audio packet contained in an earlier frame. The sample hypnotix.smk* exhibits this. It has three audio tracks and the first of the three has a longer first packet, so that the audio for the first track is contained in only 235 packets contained in the first 235 Smacker frames; the end timestamp of this track is 166696 (about 7.56s at a timebase of 1/22050); the other two audio tracks both have 253 packets contained in the first 253 Smacker frames. Up until now, the 236th packet of the second track being the first audio packet in the 236th Smacker frame would get the end timestamp of the last first audio packet from the last Smacker frame containing a first audio packet and said last audio packet is the first audio packet from the 235th Smacker frame from the first audio track, so that the timestamp is 166696. In contrast, the 236th packet from the third track (whose packets contain the same number of samples as the packets from the second track) has a timestamp of 156116 (because its timestamp is derived from the end timestamp of the 235th packet of the second audio track). In the end, the second track ended up being 177360/22050 s = 8.044s long; in contrast, the third track was 166780/22050 s = 7.56s long which also coincided with the video. This commit fixes this by not using timestamps from other tracks for a packet's pts. *: https://samples.ffmpeg.org/game-formats/smacker/wetlands/hypnotix.smk Reviewed-by: Timotej Lazar <timotej.lazar@araneo.si> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avformat/smacker: Stop caching and copying audio framesAndreas Rheinhardt2020-07-04
| | | | | | | | | | | | | | | | | | | | | The layout of a Smacker frame is as follows: For some frames, the beginning of the frame contained a palette for the video stream; then there are potentially several audio frames, followed by the data for the video stream. The Smacker demuxer used to read the palette, then cache every audio frame into a buffer (that gets reallocated to the desired size every time a frame is read into this buffer), then read and return the video frame (together with the palette). The cached audio frames are then returned by copying the data into freshly allocated buffers; if there are none left, the next frame is read. This commit changes this: At the beginning of a frame, the palette is read and cached as now. But audio frames are no longer cached at all; they are returned immediately. This gets rid of copying and also allows to remove the code for the buffer-to-AVStream correspondence. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avformat/smacker: Check audio frame sizeAndreas Rheinhardt2020-07-04
| | | | | | | The first four bytes of smacker audio are supposed to contain the number of samples, so treat audio frames smaller than that as invalid. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avformat/smacker: Avoid potential inifinite loop on errorAndreas Rheinhardt2020-07-04
| | | | | | | | | | | | | | | | | | | | | | | | | When reading a new frame, the Smacker demuxer seeks to the next frame position where it excepts the next frame; then it (potentially) reads the palette, the audio packets associated with the frame and finally the actual video frame. It is only at the end that the frame counter as well as the position where the next frame is expected get updated. This has a downside: If e.g. invalid data is encountered when reading the palette, the demuxer returns immediately (with an error) and if the caller calls av_read_frame again, the demuxer seeks to the position where it already was, reads the very same palette data again and therefore will return an error again. If the caller calls av_read_frame repeatedly (say, until a packet is received or until EOF), this meight become an infinite loop. This could also happen if e.g. the size of one of the audio frames was invalid or if the frame size was gigantic. This commit changes this by skipping a frame if it turns out to be invalid or an error happens otherwise. This ensures that EOF will be returned eventually in the above scenario.

* avformat/smacker: Don't increase packet counter prematurelyAndreas Rheinhardt2020-07-04
| | | | | | | | | | | | | | | | | | | | | | The Smacker demuxer buffers audio packets before it outputs them, but it increments the counter of buffered packets prematurely: If allocating the audio buffer fails, an error (most likely AVERROR(ENOMEM)) is returned. If the caller decides to call av_read_frame() again, the next call will take the codepath for returning already buffered audio packets and it will fail (because the buffer that ought to be allocated isn't) without decrementing the number of supposedly buffered audio packets (it doesn't matter whether there would be enough memory available in subsequent calls). Depending on the caller's behaviour this is potentially an infinite loop. This commit fixes this by only incrementing the number of buffered audio packets after having successfully read them and unconditionally reducing said number when outputting one of them. It also changes the semantics of the curstream variable: It is now the number of currently buffered audio packets whereas it used to be the index of the last audio stream to be read. (Index refers to the index in the array of buffers, not to the stream index.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* ffprobe: Allow unknown format private AVOptionsDerek Buitenhuis2020-07-02
| | | | | | | | | | | | | | | | This useful, because by ffprobe's very nature, you use it to probe a file and find out what it is. Requiring every format private option to be known to the demuxer forces one to run ffprobe twice, if one wants to use ffprobe in a generic way. For example, say one wants to probe all user-uploaded files, while also ignoring edit lists for any MP4s that are uploaded. Currently, you'd have to run ffprobe twice: once to identify the format, and once again to actually probe the metadata you want. After this patch, you could set -ignore_editlist 1 on every call and only probe once. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
