Errors from [FfmpegDemuxer].

Variants

Ffmpeg(Error)

The wrapped libavformat call reported an error — open, read or seek.

ProbeBudgetExhausted(ProbeBudgetExhausted)

libavformat asked for more bytes than the probe budget allows while opening and analysing the container. See ProbeBudgetExhausted.

AttachmentTooLarge(AttachmentTooLarge)

One attachment’s payload is over the per-attachment budget. Refused at open, before the copy.

AttachmentBudgetExhausted(AttachmentBudgetExhausted)

The file’s attachments, together, are over the whole-file budget. Refused at open, before the copy that would have crossed it.

ParametersTooLarge(ParametersTooLarge)

One stream’s codec parameters hold more heap bytes than the budget allows. Refused at open, before the clone.

ParametersBudgetExhausted(ParametersBudgetExhausted)

Every stream’s codec parameters together are over the whole-file budget. Refused at open, before the clone that would have crossed it.

ParametersMissing(ParametersMissing)

Codec parameters arrived that were never allocated.

ParametersAlloc(ParametersAlloc)

Codec parameters for a track could not be allocated.

ParametersCopy(ParametersCopy)

Copying a track’s codec parameters failed part way.

PacketBuffer(PacketBuffer)

A packet’s payload could not be referenced — the bytes are there and this layer could not carry them.

ReaderPanic(ReaderPanic)

The Read + Seek source given to [FfmpegDemuxer::open_reader] panicked inside a libavformat callback.
