* avcodec/videotoolboxenc: fix undefined behavior with rc_max_rate=0Thomas Guillem2018-07-19
| | | | | | | | | | | On macOS, a zero rc_max_rate cause an error from VTSessionSetProperty(kVTCompressionPropertyKey_DataRateLimits). on iOS (depending on device/version), a zero rc_max_rate cause invalid arguments from the vtenc_output_callback after few frames and then a crash within the VideoToolbox library.

* avcodec/videotoolboxenc: fix invalid session on iOSThomas Guillem2018-06-18
| | | | | | | Cf. comment. Restart the VT session when the APP goes from foreground to background and vice versa. Signed-off-by: Aman Gupta <aman@tmm1.net>
* avcodec/videotoolboxenc: split initializationThomas Guillem2018-06-18
| | | | | | | | | Split vtenc_init() into vtenc_init() (VTEncContext initialization) and vtenc_configure_encoder() (creates the vt session). This commit will allow to restart the vt session while encoding. Signed-off-by: Aman Gupta <aman@tmm1.net>
* avcodec/videotoolboxenc: fix mutex/cond leak in error pathThomas Guillem2018-06-18
| | | | | | The leak could happen when the vtenc_create_encoder() function failed. Signed-off-by: Aman Gupta <aman@tmm1.net>
* avcodec: add metadata to identify wrappers and hardware decoderswm42017-12-14
| | | | | | | | | | | | | | | | | | | | | Explicitly identify decoder/encoder wrappers with a common name. This saves API users from guessing by the name suffix. For example, they don't have to guess that "h264_qsv" is the h264 QSV implementation, and instead they can just check the AVCodec .codec and .wrapper_name fields. Explicitly mark AVCodec entries that are hardware decoders or most likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing API users listing hardware decoders in a more generic way. The proposed AVCodecHWConfig does not provide this information fully, because it's concerned with decoder configuration, not information about the fact whether the hardware is used or not. AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software implementations in case the hardware is not capable. Based on a patch by Philip Langdale <philipl@overt.org>. Merges Libav commit 47687a2f8aca3f65b6fdd117b1cb66a7409a7fd1.

| | | | | | | This avoids confusion with equivalent H.265 SEI values when both are being used at the same time. (cherry picked from commit 6ea220cbeec8863e2006a03b73bed52db2b13ee7)
